Did you try 'sudo apt-get update --fix-missing' and/or 'sudo dpkg --configure -a' (run this commands without quotes in the terminal)? – Alex Spataru Mar 10 '13 at 1:54

First, try this commands in the Terminal (CTLR+ALT+T):

sudo apt-get update --fix-missing
sudo dpkg --configure -a

If your problem still persists, try downgrading (using Synaptic Package Manager) the packages:

  • libc6
  • libgcc1
  • libstdc++6
  • libudev0
  • zlib1g

Tutorial about downgrading packages

Hope it helps!
