so i was trying to fix some dependency problems with my repositories and stuff and i ran

sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade

and this is what happened (some log from the start isnt shown cause that's all i could copy from my terminal)

http://paste.ubuntu.com/10156566/

i killed apt-get cause i just panicked as i saw network manager being removed, so now i just want to reinstall what i removed and would be happy if someone could explain what that command was going to do

UPDATE i suppose reinstalling a new version would be more logical, thanks for your help anyways

and i would still be happy to understand what was that command going to do if i hadnt killed it :D

I was optimistic about recovering this but having seen your apt-get update output, I can see serious issues. You have messed up the system at this point and it's uneconomical to do anything but start again.

  • You're using 12.10. This has been dead for almost a year. No more updates, repos moved. That's why you're getting so many 404s and so many packages can't be found.

  • You've added the Debian Squeeze main repo. While Ubuntu is based on Debian, they aren't directly compatible. Adding an incompatible repository is like injecting the wrong blood type. This is probably the cause of your dependency-related meltdown.

At this point, I'm not sure what's best, you could remove the Debian repo but you'd also need to track down anything you've installed from it (as it'll be conflicting with current Ubuntu's packages). You'll also need to switch from the other 404-repos to the old-releases server. Even after all that, you'll still need to upgrade to 13.04, then 13.10 and then 14.04 before you're back on a supported system with live repos.

So again, I don't think it's economical to rescue. I would struggle to rescue a system like this if I was on site. Instead I would:

  1. Create a 14.04 live USB on another computer
  2. Reboot into that on this computer
  3. Rescue my documents, etc to an external drive
  4. Do a fresh install of 14.04
  5. Read when Apt asks me if I want to continue in the future.

That'll take you about 40 minutes. Rescuing will take hours, if it is indeed possible at all.

  • i already figured rebooting would be my doom, im lucky i can still access internet :D Reading package lists... Done Building dependency tree
    Reading state information... Done E: Unable to locate package ubuntu-desktop     – Ali Ameli Feb 10 '15 at 10:43
  • Well that's worrying in itself. What's the output of sudo apt-get update? And does the install work after doing that? – Oli Feb 10 '15 at 10:44
  • fetched some packages, still not working : Unable to locate package ubuntu-desktop, maybe i could install the packages from my installation cd, but since the amount of packages which have been deleted is a lot, i think installing em one by one would be idiotic, so maybe some way to install all base packages? – Ali Ameli Feb 10 '15 at 10:49
  • When I asked for the output, I meant "Can I have the full output of ... please?" Can you stick it in another pastebin, it's relevant. – Oli Feb 10 '15 at 10:51
  • http://paste.ubuntu.com/10156839/ i think some of the servers are restricted in my country, but i have been surviving without em, so i dont think that would be a problem – Ali Ameli Feb 10 '15 at 11:01
  • It seems to me that your /etc/apt/sources.list is very old since it's trying to fetch packages for Quantal, which is not longer available. You should change all Quantal entries to an LTS (either Precise or Trusty) or a newer release. The package ubuntu-desktop is available on these releases. – aguslr Feb 10 '15 at 11:12
  • @AliAmeli Having seen that, I think this install is toast. You could probably rescue it with many hours work but you'd do much better to just backup your documents and install 14.04. – Oli Feb 10 '15 at 12:16
