• What's the risk of upgrading over SSH?

  - by C. Ross

  When I run sudo do-release-upgrade over ssh, I get the following message. This session appears to be running under ssh. It is not recommended to perform a upgrade over ssh currently because in case of failure it is harder to recover. If you continue, an additional ssh daemon will be started at port '9004'. Do you want to continue? What is the real risk of upgrading over ssh? How does the additional ssh daemon help mitigate this?

  - by user292674

  When I try to log in on my Ubuntu 12.04 it goes to a black screen ( of logging in checking stuff ), and says Checking battery ----- [ok] ( I'm using a computer instead of a laptop ) and just goes back to the login screen. Two days before I executed the command sudo startx trying to start KDE, but it didn't work. And after logging off and trying to log in again, I had this problem. A big problem is that I don't have internet connection at home. What should I do?

• Setting up the GDM Theme

  - by Szymoninho

  I'm using Ubuntu 12.04 with Gnome Classic (no effects) and because of the fact that some system options have disappeared with the new system release I've been struggling with this for a while and despite this seems very easy I can't do this :/ - does anyone know how to choose a GDM Theme? I'm quite sure that GDM is now in use on my Ubuntu - I set it up with: sudo dpkg-reconfigure gdm Despite I moved the theme folder to /usr/share/gdm/themes nothing has changed by now, I've logged out and in a couple of times but everytime I get the standard log in window and wallpaper (different from mine). So I'll appreciate any kind of help from anybody, now I have absolutely no idea how to figure it out. Cheers.

• No Windows Option on Boot

  - by Okoning

  I've installed Ubuntu alongside Windows but at first didn't have a boot option menu. So, I installed bootrepair and ran it. This succeeded in granting me a GRUB boot option menu, but Windows isn't on it. Here is the bootrepair report: http://paste.ubuntu.com/8098527 Can anyone tell me what might be wrong? EDIT: I ran sudo fdisk -l and this is the output: Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00023fe0 Device Boot Start End Blocks Id System /dev/sda1 * 2048 960096255 480047104 83 Linux /dev/sda2 960098302 976771071 8336385 5 Extended /dev/sda5 960098304 976771071 8336384 82 Linux swap / Solaris Disk /dev/sdb: 32.0 GB, 32015679488 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62530624 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 * 32 62530623 31265296 c W95 FAT32 (LBA)

Any Idea how to solve it? Thank you!

• How to install libdvdcss?

  - by skwd

  I'm relatively new to Ubuntu and I'm trying to figure out how to play DVDs. I've read through a lot of forums, and got to the one asking how to read encrypted DVDs. I was able to do the first step and installed libdvdread4, but when I got to the second step of installing libdvdcss, I got what amounted to error messages. This is the command I ran: sudo /usr/share/doc/libdvdread4/install-css.sh Is there something important that I should know? As in, probably something basic that I don't know because I'm new...?

• Why do I get this error trying to compile libxml2?

  - by bfaskiplar

  Although, I installed libxml2 once and reinstalled it for a few times. I cannot compile c-source code because compiler cannot find where the header file is. I am able to locate where it is (in the folder where I downloaded the tar.gz package) but I had a feeling in my guts that this package isn't installed correctly because when I tried to sudo make install, it says /bin/bash: /home/bfaskiplar/Downloads/tar.gz: No such file or directory make[2]: *** [install-libLTLIBRARIES] Error 127 make[2]: Leaving directory `/home/bfaskiplar/Downloads/tar.gz packages/libxml2-2.8.0' make[1]: *** [install-am] Error 2 make[1]: Leaving directory `/home/bfaskiplar/Downloads/tar.gz packages/libxml2-2.8.0' make: *** [install-recursive] Error 1 that's why I installed synaptic package manager and reinstalled it, but in this case, isn't it supposed to put header files in default directory where gcc normally searches in currently, I am able to compile it with -I option, but I wonder why do I have to copy headers manually even if I used synaptic for installation and why I am getting Error 1 and Error 2 when trying to install the package manually. thanks in advance

• Using "MTNL 3G Jadoo" data card on Ubuntu

  - by amolbk

  I am trying to use "MTNL 3G Jadoo" data card (Teracom LW272) with Ubuntu 12.04. On connecting, it gets mounted as a drive containing the client installation .deb file. I opened the .deb file in Ubuntu Software Center and installed it. I searched for "MTNL" in Ubuntu search and found "MTNL 3G Modem" application. But it won't run. I found it is installed in /opt/MTNL-3GModem. I tried running it from the terminal as: sudo /opt/MTNL-3GModem/ModemClient, but no luck. Any idea how to get it working?

• What should be the correct ownership of /tmp /var /usr and subdirectories?

  - by sbergeron

  For some reason I think the permissions of those were messed up from a small amount of disk corruption I had. This may be a dupe, I don't know but I googled it and didn't find any mention of it. I need to know how the permissions of them should be set up as currently my computer can't actually use the tmp directory and I can't download anything consequently. I have access to the recovery mode command line but while in sudo user prompts it doesn't seem to work correctly. Also something is wrong with package management and I get dpkg: error: unable to access dpkg status area: read-only file system. I know my system is really messed up but I don't want to have to reinstall AGAIN.

• Build multiple sources into multiple targets in a directory

  - by Taschetto

  folks. I'm learning about GNU-Make and I have the following project structure: ~/projects /sysCalls ex1.c ex2.c ex3.c ex4.c ex5.c ex6.c ex7.c Each .c source is very simple, has its own main function and must be built into a corresponding binary (preferably named after its source). But I want to build into a bin directory (added to my .gitignore file). My current Makefile is: CC := gcc CFLAGS := -Wall -g SRC := $(wildcard *.c) TARGET := $(SRC:.c=) all: bin $(TARGET) mv $(TARGET) bin/ bin: mkdir bin clean: rm -fr bin/ It works as expected, but always builds every source. And I don't like moving everything to bin "manually". Any tips or ideas on how this Makefile could be improved?

• knetworkmanager not starting at all

  - by yoshi

  It seems that my knetworkmanager is not starting anymore. Read: In KDE4's sys tray I don't have a icon to manage my networks. Also when starting it from terminal or kick off menu literally "nothing" happens. I don't know what's wrong with it. Sadly after reading this answer on superuser.com it seems I can not connect to wifi via iwconfig 'cause my network is WPA2 encrypted. (Basically I can not set they passphrase - invalid argumenterror.) So it seems I've to get knetworkmanger running again as I also can't download other tools. I've tried stuff like sudo service network-manager restart but it didn't seem to help. I'm kinda puzzled so any help for this would be appreciated. PS: If it hasn't become clear: The whole drama of is simply I can't connect to wifi and internet :o)

• How do I allow a non-default user to use serial device ttyUSB0?

  - by lucaghera

  I have an Ubuntu 11.10 system with 2 users: The first was created during the installation The second instead was created after. It belongs to the sudoers group. Now the problem is that when the second tries to use a device ttyUSB0 the following error is returned: "Could not open serial port /dev/ttyUSB0" I was able to fix it by using: sudo chown :second_user /dev/ttyUSB0 However when I disconnect the device and reconnect it the problem comes back. Is there a way to allow different users to access the devices? I suppose I have to add the user to a specific group. Currently the owner is root and the group is dialout. However I'm not sure about the group and I don't know how to add the user. Thanks!

• GUI is not displayed anymore

  - by mdobrinin

  I am running 12.04 LTS on a VM. I encountered a problem with the screen being black and the familiar orange background showing for a fraction of a second when clicking or resizing the screen. I had to shutdown the machine and now I have no GUI. I only get a black command-line interface. As some other posts suggest, I attempted: sudo service lightdm restart This doesn't work for me because it gets stuck at this point: Skipping profile in /etc/apparmor.d/disable: user.bin.firefox Skipping profile in /etc/apparmor.d/disable: user.sbin.rsyslogd * Starting AppArmor profiles [ OK ] Any ideas?
