I can't install anything right now (or upgrade anything). When I run `sudo apt-get upgrade I get this list of unmet dependencies. At the end it says

E: Unmet dependencies. Try using -f.

When I try sudo apt-get upgrade -f I get

E: Could not perform immediate configuration on 'libc6'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

Nothing happens though. I don't really know what's going on, or how to troubleshoot this. I looked at man 5 apt.conf under Immedate-Configure, but it didn't really tell me anything.

I'm kind of skeptical that all these things need to be installed. I think there's just an error reading some package list or something, so it doesn't know what's installed or not. But I could be wrong about that.

How can I fix these dependency issues?

  • Maybe some packaging error on myunity's side? Try to disable that PPA and see what happens if you do a: sudo apt-get update && sudo apt-get upgrade – Timo Feb 26 '12 at 18:18

I just ran

sudo apt-get -o APT::Immediate-Configure=no upgrade

using someone else's suggestion. After that I ran

sudo apt-get autoremove

and together they seem to have fixed the issue. I'm not sure how it happened though.

That suggestion from the tool is a bit ambiguous if not misleading. You are supposed to run sudo apt-get install -f and NOT sudo apt-get upgrade -f.

Read more about the -f option in man apt-get. It is a bit dense, but it says that -f is expected to work with apt-get install and apt-get remove.

  • apt-get install -f gave me similar messages. – Kris Harper Feb 26 '12 at 18:31
  • Try getting into single user mode and running this again. The package list shown will probably not be downloaded and installed (it says 0 bytes to download). It is probably some aborted installation earlier which left some packages unconfigured.

    Since libc6 is practically used all the time when you are doing real work, maybe going into single user mode can help you fix it.

  • Never mind. Saw your answer up there. :) – Sandip Bhattacharya Feb 26 '12 at 18:49

I had a similar packages dependencies problem (Ubuntu 12.10). I fixed it by unticking (in the Software Sources Updates tab):" Pre-released updates (quantal-proposed) " and " Unsupported updates (quantal-backports) "

Worked for me!

Some times it's something as easy as that other times? Not so..................
