• How do I install OpenStack?

• ISO Live Session from an External Hard Drive?

  - by amemus

  Is it possible to use an external hard drive to start a live Ubuntu session? Is having an ISO file as the whole content of the first partition of the device enough? Thank you for reading...! EDIT upon reading the first comment to my original question: If I remember correctly, I COULD run a live session of Oneiric Ocelot somehow. It was not from a CD because I failed to burn one, so it must have been from an ISO file. Still very very confused....

• Cannot install build essential from the CD?

  - by munir

  After a fresh installation of Ubuntu 10.10 I tried to install build-essential from the Ubuntu installation CD. I put the cd in the cdrom and in the software repositories i checked the box install from cd(Ubuntu 10.10 release Maverick Meerkat). Then I reloaded the software repositories. The synaptic manager then tried to download some repository related files but failed to do so as i didn't have internet connection. Then I open a terminal and wrote sudo apt-get install build-essential. It prompted me if I want to install build essential y/N. I typed y but the terminal showed some errors and was not installed. I also tried to add the CD in the software repositories. I clicked add and it prompted me to insert a CD while the CD was still inside the cdrom. I clicked "ok" then and it showed it could not find any cd. What is wrong?

• Upgrade from ubuntu 9.10 to 11.10

  - by Chinnu

  Our project definition is to develop CUDA programs. Our workstation has CUDA 3.1 installed in Ubuntu 9.10. We need to program in CUDA 5.0 which can be installed only on ubuntu 11.10 or 12.04. We tried upgrading but were faced with many problems as 9.10 is no longer supported. So we chose to proceed with a clean installation. Since we have a shared workstation, we need to back up the settings. We decided to use clonezilla for cloning the system. Booting from the LiveCD showed an unexpected error. Another option was to install 11.10 in an external HDD by partitioning it, but Gparted could not be installed and terminated with the error "installArchives() failed" which we couldn't solve even after modifying the sources.list. We are stuck either ways. Have no idea how to proceed and we have a deadline to submit our CUDA program. Any suggestion is welcome.

• How to refuse to give an access to passwords to a customer without being unprofessional or rude?

  - by MainMa

  Let's say you're creating a website for a customer. This website has its own registration (either combined with OpenID or not). The customer asks you to be able to see the passwords the users are choosing, given that the users will probably be using the same password on every website. In general, I say: either that it is impossible to retrieve the passwords, since they are not stored in plain text, but hashed, or that I have no right to do that or that administrators must not be able to see the passwords of users, without giving any additional details. The first one is false: even if the passwords are hashed, it is still possible to catch and store them on each logon (for example doing a strange sort of audit which will remember not only which user succeeded or failed to logon, but also with which password). The second one is rude. How to refuse this request, without being either unprofessional or rude?

• Cannot upgrade or install 12.04 - Black screen

  - by Paul

  An update from 11.10 to 12.04 failed because of a boot into black screen (Nvidia graphics card) after selecting normal boot in Grub (recovery console was available though). I then wiped the whole partition (deleting all proprietary drivers) and tried a fresh install, but could not run the installation cd because it was booting straight into a black screen again. Now I reinstalled 11.10 (and installed proprietary Nvidia driver version 173), and would like to ask 2 questions: 1 - Is there a proven method to fix this problem from the recovery console, so that I can safely try upgrading again (without much knowledge of Ubuntu)? 2 - Is there a website which I could check for updated Nvidia drivers packaged into the upgrade, so that I can safely upgrade without running into a black screen some time later on?

• Apt Configuration problem

  - by Paul

  I am trying to load v11.04 onto my HP desktop hard drive using a USB drive. I used the same USB drive to load the system on my Dell netbook and it loaded successfully. But trying to load on the desktop I get the error " Apt configuration problem. An attempt to configure apt to install additional packages from the CD failed" The installer then crashes. I have nothing in the CD drive. I can boot the system from the USB drive and it works fine. I have tried all options on the load with the same crash each time. I baffled as I successfully loaded my netbook with the same USB with no problems.

• How to fix additional STA driver installation error on 12.04

  - by nibl

  I have a Broadcom BCM4313 wireless driver. It worked fine under 11.04 and the upgrade to 11.10 also went smoothly. The 12.04 upgrade has broken the wireless connection. I've seen several posts about this and all presume you can activate the STA drivers, but that's where it fails on this machine. The log is in /var/log/jockey.log: WARNING: modinfo for module wl failed: ERROR: modinfo: could not find module wl WARNING: /sys/module/wl/drivers does not exist, cannot rebind wl driver DEBUG: BroadcomWLHandler enabled(): kmod disabled, bcm43xx: blacklisted, b43: blacklisted, b43legacy: blacklisted (repeat of last error several times) Any ideas how to proceed?

• Change administrator username

  - by Fazlan

  I have accidentally typed my name wrong when I created the administrator account. Although I managed to change the user name at the login screen, I am unable to rename the /home/oldusername to /home/newusername. I tried most of the online tutorials, and it failed. The code I tried was this: usermod -l newusername -m -d /home/newusername oldusername But the output is: cannot lock /etc/passwd; try again later. How can I fix the issue and change the folder to newusername and expect all the applications to work as before?

• Not enough space left in the hard drive. How to proceed?

  - by jimbobjgr

  Where do I begin... I can hardly do anything on Ubuntu 12.04. I am very close to removing and returning to Windows.

I tried trouble shooting this issue but every time I try and fix the problem I am blocked by this message E: Write error - write (28: No space left on device) E: Can't mmap an empty file E: Failed to truncate file - ftruncate (9: Bad file descriptor) E: The package lists or status file could not be parsed or opened. $ OLD=$(ls -tr /boot/vmlinuz-* | head -n -2 | cut -d- -f2- | awk '{print "linux-image-" $0}') Ubuntu is also running incredibly slow and I cant get anything done! Please help this is driving me mad!

• How do I tell my boss he made the wrong choice? [migrated]

  - by SomeKittens

  Recently, our biggest product failed majorly because we'd only used outsourced labor to do it, and they never tested anything, etc. Finally, our CEO decided that the US team should learn the code and fix it up. (Not a total rewrite, but lots of formatting/style changes, refactoring, etc). However, he knows next to nothing about programming (thankfully, he admits it). He had been grooming me to take on the project manager position, but I had to go back to college. Now he gave it to another programmer who is naive and inexperienced. I don't feel the naive programmer will do nearly as well. The CEO's reasoning is that the naive programmer can work full time and I can only do part time, so the less senior programmer could put more work into it. How can I convince him that 15 hours of my time is worth more than the other guy's 40?

• I cannot log in after theme change

  - by sssuizaaa

  After changing the gtk-theme in the gnome tweak took I was taken out of the session to the login screen and now I cannot log in. I can only log in using the guest account. So in the grub menu I selected the recovery mode and in the resulting menu I selected root-drop to root shell prompt. Once there I did a couple of things I've found in several pages and in the forums. 1.gsettings reset org.gnome.desktop.interface gtk-theme This is what I got: (process:642):WARNING: Command line 'dbus-launch –autolunch=4438d024dd45ef7fb2d3f4ab0000000f –binary-syntax --close-stderr' exited with non-zero exit status 1: Autolaunch error: X11 initialization failed.\n and nothing changes 2.gconftool-2 --type=string -s /desktop/gnome/interface/gtk_theme Radiance with this I was trying to change the gtk theme to the Radiance one. No strange message this time but it did not work either. I still cannot log in. Any ideas please?? sssuizaaa

• Ubuntu won't stay installed

  - by tommythm227

  I recently experienced OS problems with Windows 8 so I decided to wipe my hard drive and install Ubuntu using a usb boot. I am able to "Try Ubuntu" or choose to install instantly, however, after installation it asks me to restart my computer but when I do this I receive the same installation options I originally had, "Try Ubuntu", "Install", "OEM Install", "Repair Disk". I initially thought this was the result of leaving the boot usb in, so I tried reinstalling, but now I just receive a message saying "No boot disc or boot disc failed". This happens with any type of install I do, I've tried clearing the hard drive multiple times, making a new boot usb, but nothing seems to help. I've tried reinstalling windows, but I encounter the same problem, without the usb I get an error. I have an Acer Aspire M3470, I cleared my hard drive and attempting to install via usb boot. I have a weird BIOS menu probably because of AMD but it's been hard to find information regarding my particular BIOS menu. HERE is an image of my BIOS menu

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?

• Only sdb shows up when installing 12.04 on new Dell inspiron 14z

  - by Jan Korpegård

  I got my brand new Dell Inspiron 14z yesterday, but failed to install Ubuntu. I can boot from a USB stick, and it works well. When trying to install, I confirm that the laptop is connected to the internet etc (as in the 2nd picture in the installation guide: How do I install Ubuntu?). When pressing "Continue" I do not get the question on installation type (alongside/replace/something else). Instead I get a window where I can select partitions: // Picture removed due to low reputation... The problem is that I can only select sdb in the drop drop down box, and I can do do nothing with sdb (like adding partitions etc). The main disk (sda) is partitioned using Gparted the following way: // Picture removed due to low reputation As far as I understand from other threads on askubuntu, this should work... What can I do to install Ubuntu alongside with Windows 7?

• Is it possible to have my desktop loaded before login?

  - by Dims

  I am connecting to the system with Putty (this is Windows SSH client) then running some service in interactive personal mode. For example this is a script to run freeswitch: dims@nebulla:~$ cat freeswitch.sh #!/bin/sh cd ~/bin/freeswitch/bin gnome-terminal -e ./freeswitch & I.e. it is installed in user directory. Also DISPLAY is set to :0 The problem is that I can't use this script until login once. Script responds with dims@nebulla:~$ ./freeswitch.sh dims@nebulla:~$ No protocol specified Failed to parse arguments: Cannot open display: After login, I can do "Switch user" and see login screen but script will be able to run since desktop exists. My question is: is it possible to "preload" my desktop, so that initial situation was as if I loogged in and the went to switch user?
