• Why does integrity check fail for the 12.04.1 Alternate ISO?

  - by mghg

  I have followed various recommendations from the Ubuntu Documentation to create a bootable Ubuntu USB flash drive using the 12.04.1 Alternate install ISO-file for 64-bit PC. But the integrity test of the USB stick has failed and I do not see why. These are the steps I have made: Download of the 12.04.1 Alternate install ISO-file for 64-bit PC (ubuntu-12.04.1-alternate-amd64.iso) from http://releases.ubuntu.com/12.04.1/, as well as the MD5, SHA-1 and SHA-256 hash files and related PGP signatures Verification of the data integrity of the ISO-file using the MD5, SHA-1 and SHA-256 hash files, after having verified the hash files using the related PGP signature files (see e.g. https://help.ubuntu.com/community/HowToSHA256SUM and https://help.ubuntu.com/community/VerifyIsoHowto) Creation of a bootable USB stick using Ubuntu's Startup Disk Creator program (see http://www.ubuntu.com/download/help/create-a-usb-stick-on-ubuntu) Boot of my computer using the newly made 12.04.1 Alternate install on USB stick Selection of the option "Check disc for defects" (see https://help.ubuntu.com/community/Installation/CDIntegrityCheck) Steps 1, 2, 3 and 4 went without any problem or error messages. However, step 5 ended with an error message entitled "Integrity test failed" and with the following content: The ./install/netboot/ubuntu-installer/amd64/pxelinux.cfg/default file failed the MD5 checksum verification. Your CD-ROM or this file may have been corrupted. I have experienced the same (might only be similar since I have no exact notes) error message in previous attempts using the 12.04 (i.e. not the maintenance release) Alternate install ISO-file. I have in these cases tried to install anyway and have so far not experienced any problems to my knowledge. Is failed integrity check described above a serious error? What is the solution? Or can it be ignored without further problems?

• Synchronising Cut-and-Paste Activities in Ubuntu One

  - by Jackson Tan

  This was posted in the Ubuntu Forums but received no response, so I'm re-posting it here (with minor updates) in hopes that it will at least get some comments. Recently, I moved a large amount of contents (a few GBs) within the Ubuntu One folder (through cut-and-paste). Then I discovered how Ubuntu One does this is to remove them on the server side and upload all the files again in the new location. Obviously, this is undesirable because of the hefty uploading involved. Worse, since I have two computers synced to the same account, it is double the amount of traffic. Each computer took about one day to finish synchronising. Firstly, can anyone confirm that this is actually what's happening when we move folders? I'm using Ubuntu 10.04, by the way. Secondly, is there a way to cut-and-paste stuff within the Ubuntu One folder without uploading again?

• Samba smb.conf read only and read/write accounts

  - by Pieter

  Below you can see my smb.conf, pieter is my admin user read/write on the shares works good with that account. Then I have a leecher account that has been added with smbpasswd -a leecher to the smb users, it is set up so this user only has read access to the shares. This works on MegaSam and on Thumbnails but not on my other drives, leecher does not get any access on the other shares. [global] security = user [MegaSam] comment = MegaSam path = /media/MegaSam browsable = yes guest ok = no read list = leecher write list = pieter create mask = 0755 [SilentBob] comment = SilentBob path = /media/SilentBob browsable = yes guest ok = no read list = leecher write list = pieter create mask = 0755 [Thumbnails] comment = Thumbnails path = /media/Thumbnails browsable = yes guest ok = no read list = leecher write list = pieter create mask = 0755 [Downloads] comment = Downloads path = /media/Downloads browsable = yes guest ok = no read list = leecher write list = pieter create mask = 0755

• What is the proper way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?

  - by Denja

  Hi Linux Community, I find my self struggling with the slowness of windows OS once again. It's Time to change with the Ubuntu 10.10 64bit for I like to use a faster Operating System. My Hard Disk laptop has a RECOVERY and HP_TOOLS partition they are both Primary. I Have the System Recovery DVD for Windows 64bit should anything bad happen. Here's the layout I used with windows before: * (C:) Windows 7 system partition NTFS - 284,89GB (Primary,ad Boot,Pagefile,Dump) * HP_TOOLS system partition FAT32 - 99MB (Primary) * (D:) RECOVERY partition NTFS - 12,90GB (Primary) * SYSTEM partition NTFS 199MB (Primary) Here's the layout I wanted to make: * (C:) Windows 7 system partition NTFS - 60GB (Primary) (sda1) * (D:) Windows DATA partition (user files) NTFS - 120GB(Primary)(sda2);wanna share with Linux * Linux root Ext4 - 10GB (Extended)(sda3) (Ubuntu 10.10 64bit) * Linux home Ext3 - 90GB (Extended)(sda4) (Ubuntu 10.10 64bit) * Linux swap swap- RAM size, 3GB (sda5) * Linux root Ext3- 18GB (Extended) (sda6) (OpenSuse or Puppy or kubuntu) Here is my New Ubuntu 10.10 64bit layout in use now: * SYSTEM partition NTFS 199MB (Primary) (sda1) * (C:) Windows 7 system partition NTFS - 90GB (Primary) (sda2) * (D:) Windows 7 RECOVERY partition NTFS - 12,90GB (Primary) (sda3) * Linux system partition EXTENDED - 195,1GB (Logical) * Linux root Ext4- 10GB (Extended) (sda4) * Linux swap swap- RAMx2 size, 6,1GB (sda5) * Linux home Ext3- 179GB (Extended) (sda6) When I installed Ubuntu,I didn't know if I could wipe all previous partitions,because of the RECOVERY partition. So I just made the space for my extended partition with GParted by deleting the HP_TOOLS (Fat32). By doing this I managed somehow to install Ubuntu 64 with Success. And I also made the partitions for the swap or a third Linux OS as Jordan suggested. But I couldn't actually make the partitions for the shared NTFS.(no option!) Question 1: What is the proper way to Windows 7/Ubuntu 10.10 Dual-Triple Boot Partitioning for Laptop OEM?? Thank you in advance for your advises and suggestions and Happy New Year to All!!

• Screen magnifier wrecks login screen — how to get rid of it?

  - by Jonik

  In the Ubuntu / GNOME login screen, I tried some of the different accessibility settings out of curiosity. Big mistake! Enabling the "use screen magnifier" (or whatever) option breaks down the view horribly, and makes it impossible to even access the settings again: (Right click & View Image for full size) Yes, I tried to access every corner of the screen using the mouse, but there's just chaos everywhere. Fortunately, I can still log in (pressing "Esc" makes the normal login dialog appear on the left-hand monitor). My question is, how to disable the "magnifier" option outside of the login screen itself? (By editing some config file perhaps?) I don't care about getting the magnifier mode to work properly - just make it go away altogether, please.

• Help! Online upgrade from 12.04 to 14.04 stuck

  - by Luis

  I was trying to upgrade my Lenovo T500 laptop from Kubuntu 12.04 LTS to Kubuntu 14.04 LTS. Fired up the upgrade process, and finally after downloading a zillion packages the upgrade got going, only to get stuck... It has been stuck for hours on: Installing the upgrades->Unpacking subversion Last lines of error messages: GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.32.4/./gobject/gtype.c:2722: You forgot to call g_type_init() at /usr/lib/perl/5.18/DynaLoader.pm line 207. GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed at /usr/lib/perl/5.18/DynaLoader.pm line 207. I don't care much about subversion anymore, I use git now; I don't care if subversion ends up in a bad state and I have to remove it... I just want the upgrade to continue, and hopefully complete. Any ideas???? Thanks, Luis

• Songs bought from the Ubuntu One Music store showing Unknown Album/Artist in streaming app

  - by rotard

  I've been using Ubuntu one for several years and have purchased several albums from the Ubuntu One music store. All was well while I was playing them from Rhythmbox or Banshee. However, I recently started using the U.O. streaming android app and streaming section of the one.ubuntu.com website and most of my music appears to be untagged. What is going on? Before this question is dismissed as a duplicate, let me reiterate the crucial differences: ALL of the music in my U.O. account was bought in the Ubuntu One music store. This is NOT music that I ripped or bought elsewhere The mp3s that end up on my hard drive DO appear to be tagged correctly The issue affects the U.O. Streaming Music Android app AND the website (viewed in Chrome on my Win7 work PC) Is this some problem with the streaming service? Is there anything I can do?

• What is better Ubuntu Tweak or Software center?

  - by S B

  Ubuntu Tweak has served me very well over the past few release cycles, but there seems to be more and more of an overlap between Ubuntu Tweak and the Ubuntu Software Center. I wanted to know whether these two great apps are headed for a head-to-head crash (which would be a shame for the Ubuntu community) or is there some way for the two projects to complement each other, integrate and make my favorite distribution even better? Happy new year to everyone.

• Windows 7 restarts PC when selected from GRUB Menu

  - by Dan Still

  I installed windows 7 on a RAID 5 (2@160GB SATA +1@160GB SATA for RAID 5) I then proceeded to install Ubuntu 11.10 using the Live CD and opted: "Install along side Windows 7 Option" Upon boot GRUB appears normally and I can select and run Ubuntu with no difficulties. When I select Windows 7 from GRUB the PC restarts and consequently goes back to GRUB. I have attempted to use the Windows 7 DVD to repair the installation but to no avail. The Wizard ran twice as it described it might, after the second attempt came back with an '...inability to repair...' error. I am sure there is an answer to this somewhere but I have yet to be able to find it. (2 weeks and countless attempts and searches before posting this question. Although I am happy to use Ubuntu alone my wife likes to watch Netflix and therein requires the Windows 7 installation. Any answers are appreciated and welcomed. Thanks in advance. Dan Still

• How can I run sudo gedit as gksu gedit

  - by SimplySimon

  I'm looking into ways of automatically loading Gedit as gksu gedit when I enter sudo gedit by mistake? I have found that I have made a number of files unreachable by using gedit and I have only just found out why! ACHIEVED SO FAR I have written a script which will make an alias so that if I type in sudo <application> it can automatically convert that to gksu <application> but I want to make this alias stick, so that I don't have to run the script every time I boot the computer. Is there a config file I can edit or should I run this script as a start up script (which would be inconvenient!)?

• Ubuntu 11.10 cannot boot. It stucks at BusyBox

  - by Ivan Dokov

  I am using Ubuntu 11.10. An hour ago I had my laptop Sony Vaio VPCEB1S1E running. I saw there are updates to install and I installed them. Turned off the laptop and now when I want to turn it on. It loads until BusyBox v1.18.4 appear. I've saw what the people suggest in other askubuntu topics. I've booted Puppy Linux from USB, repaired the partition where the Ubuntu is installed. Rebooted and nothing changed. I saw other suggestions like writing "exit" in the command line when the BusyBox comes. This didn't help neither. I love the Ubuntu OS, but these days I get similar problem with not able to boot OS. The last times I could repair it with Gparted, but then it wasn't problem with the BusyBox, it was something missing in the OS, like "cannot boot /". The same problem occurred on an older version of Ubuntu 10.10 and there I've repaired it again with Gparted.

• Unable to install updates on 14.04 LTS

  I have been getting update notifications for a few weeks now but whenever I attempt to install them I get this message; The upgrade needs a total of 74.6 M free space on disk '/boot'. Please free at least an additional 29.8 M of disk space on '/boot'. Empty your trash and remove temporary packages of former installations using 'sudo apt-get clean'. First of all I don't have permission to access /boot (don't know why as its a standalone machine and i'm the only user). Secondly, I emptied the trash; Thirdly, I launched Terminal and entered sudo apt-get clean I was a asked for a sudo password. I entered my system password. Re-entered sudo apt-get clean. The cursor stopped blinking - I assumed it was doing it's "thing". I let it go for about 10 minutes then exited Terminal. Tried to install the updates but just got the same message. Is there something i'm ignorant of?

• file error /boot/grub/i386-pc/normal.mod trying to repair boot, live dvd install probleml

  - by user179295

  I have seen that there are a lot of threads about this problem. I had Windows 8 installed on my series 3 samsung i5 computer and I tried to install ubuntu 13.04. This is what I did: Because of the secure boot I can't install ubuntu from the dvd. So I went in the bios and disabled secure boot and enabled ''CSM''. I went out of the bios and windows 8 couldn't boot more. So I follow a guide on this thread ( Installing on a Pre-Installed Windows 8 System (UEFI Supported) ) and on ubuntu I tried to repair the boot by inserting this code in the terminal: sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install boot-repair Then I ran boot-repair and I follow all the steps. Then I reboot the sistem and saw the black screen that says: error: file '/boot/grub/i386-pc/normal mod' not found grub rescure> Now I saw a lot of guides about this problem but I can't understand how to reistall ubuntu trough the live dvd that I used to install it the first time... I put it in the computer but nothing appears.. so what should I do now? I'm a noob on ubuntu and I have read all the things about this grub 2 install and know where the problem comes from but how to start the dvd??

• Is it Okay to use Natty kernel in Lucid system?

  - by Anwar Shah

  I have seen some people saying to install the kernel of Ubuntu 11.04 (probably 2.6.38..) to use on Ubuntu 10.04 (2.6.35...may be) to only be able to use a Wimax device driver without upgrading their whole Ubuntu System. I find in this method something wrong, but I cannot argue as they are saying that it is OK!!. I tried to insist to upgrade to the latest Ubuntu version with all the software. But I also have the question myself : Does upgrading only the kernel is Okay ? or in other words, Is it OK to have Lucid (10.04) system with Natty(11.04) kernel (by adding Natty's repository and removing it after upgrade). What are the possible problems ? What about using Precises' kernel in Lucid system?

• black screen after waking up from suspend

  - by Daniel De Leon

  running 11.10 and on wake up after being suspended (for a long time or 2 seconds, doesn't matter) I am presented with a black screen that just has a purple bar (about the size of the top menu bar). As far as I can tell the system is unresponsive to anything outside of a manual restart by pressing the power button on the tower, after which it starts normally. using the most up to date graphics driver, also tried switching to a different version, nothing. just switched back to Linux and this is really giving me a headache, I would really like this to work. Any help would be greatly appreciated.

• How do I keep my Huawei E3131 3G modem from unmounting?

  - by John Perez

  I need help getting my Huawei E3131 modem to (consistently) work. I am currently running Ubuntu 12.04.2 and 3G dongles have worked many times before. However, my newly acquired Huawei E3131 is causing problems. When plugged in, Ubuntu detects the device as a CD-ROM and a modem. I can browse the dongle's contents using Nautilus and Network Manager is able to configure and work the dongle out-of-the-box. I can even get to surf. However, within minutes, the connection drops and the CD-ROM is unmounted. I wait about 15 seconds, then the CD-ROM mounts again and Network Manager is able to connect again with short-lived surfing. Rinse, lather and repeat. It's strange that the device mounts as a CD-ROM, but works as a modem, too, suggesting that mode switching happens somewhere. It's not a signal coverage problem, either because I tested the same SIM card using 3 other different dongles (2 ZTEs and another Huawei) and it is only this E3131 that has this problem. If pertinent, the other dongles weren't being detected as CD-ROMs. Output of lsusb Bus 001 Device 002: ID 8087:0020 Intel Corp.

Bluetooth 2.1 Device I tried installing the drivers found here, but no fish. Furthermore, my device is an E3131, but lsusb for some reason detects it as an E398. I'm not sure how that plays a role for this problem, though. I hope someone out there can help me. I'm out of ideas already. Thank you very much!

• How to create scripts that create another scripts

  - by sfrj

  I am writing an script that needs to generate another script that will be used to shutdown an appserver... This is how my code looks like: echo "STEP 8: CREATE STOP SCRIPT" stopScriptContent="echo \"STOPING GLASSFISH PLEASE WAIT...\"\n cd glassfish4/bin\n chmod +x asadmin\n ./asadmin stop-domain\n #In order to work it is required that the original folder of glassfish don't contain already any #project, otherwise, there will be a conflict\n" ${stopScriptContent} > stop.sh chmod +x stop.sh But it is not being created correctly, this is how the output stop.sh looks like: "STOPING GLASSFISH PLEASE WAIT..."\n cd glassfish4/bin\n chmod +x asadmin\n ./asadmin stop-domain\n #In order to work it is required that the original folder of glassfish don't contain already any #project, otherwise, there will be a conflict\n As you see, lots of things are wrong: there is no echo command is taking the \n literaly so there is no new line My doubts are: What is the correct way of making an .sh script create another .sh script. What do you thing I am doing wrong?

• keyboard layout switching on restart

  - by zidarsk8

  I have two keyboard layouts that I use, My default keyboard is an USA layout, with a secondary Slovenian layout. I use the Slovenian layout only when I need some special characters when writing emails and such. But my problem is this: Every time I reboot my computer, the layout indicator shows I am on the USA layout, but the actual keyboard layout is Slovenian. Then I normally have to switch from USA to Slovenian and back, to get the layout I want. Is there anything I can do about this? I don't restart my computer often, but when I do I forget about that, and typing the passwords like that doesn't work.

• Is there any way to stop a window's title bar merging with the panel when maximised?

  - by Richard Turner

  I'm working on a desktop machine with plenty of screen real-estate, so I don't need my windows' title bars to merge with the global menu bar when the windows are maximised. Moreover, I'm working on a dual-screen set-up, so the fact that a window is maximised doesn't mean that it's the only window visible. Before Unity I'd switch to a maximised window by clicking on its title bar, or close the window, even though it isn't focused, by clicking on its close button; I can no longer do this because the title bar is missing and the global menu bar is empty on that screen. This isn't a huge problem - I can click on some of the window's chrome to focus it - but it's unintuitive and it's forcing me to relearn my mousing behaviour. I'd like to turn-off the merging of title and global menu bars, but how? EDIT: I simply want the title bar of the window NOT to merge with the top panel whenever I maximize a Window. The global menu should stay in the top panel as far as I am concerned. Current it maximizes like this I want it to maximize like this (In that screeny the unmaximized Window has been resized to take rest of the space)

• Delete corrupted folder

  I am trying to delete a folder in my home directory; its name is completely garbled. In Nautilus, the garbled text is followed by 'Invalid Directory.' Deleting it with Nautilus stalls; I can't type in the garbled name in the terminal. peter@io_vbox:~$ ls -lbdR * ... drwxrwxr-x 3 peter peter 4096 Jul 28 15:19 \346>\3152\357+\332)\363*\356,\253-\277+H&\266\033z\v\373\366\340\340?\314\022\274P\262\003\260?\303p\326\342\351\214\374f\016X\036r)!.\026 ... Any ideas? Running 12.04; if it's of any importance, this is running in VirtualBox on a Macbook Air. It was installed through VirtualBox. I don't have any other signs of SSD failure that I've picked up on -- referring to this question: Random files (invalid encoding) appearing in home directory Thanks

• Uploading to a PPA using quickly

  - by Andres

  I am trying to participate in ubuntu showdown. I followed Jono's tutorial to do a browser using quickly. I did some modifications including choosing license (gpl v3), putting my name in copy right ( without special spanish charecters since quicky does not like it) $quickly run to make sure it worked I used bazaar to commit a change with a line of comment. I packaged it using quickly. Managed to install it ignoring some warnings but it would not run. I want to share code to get feedback. I have a launchpad account, signed terms and coditions, created a ppa. I got my commandline to talk to lauchpad using the encription key. But when I run $quickly release or $quickly share and it says the project does not exist. There seems to be another command $dput ... But i don't seem to get the wording right because it requests some sort of signed file that i cannot manage to add the correct way.
