I'm having some trouble updating my software. It seems like the new packages have been downloaded but one package is giving me some trouble

This is the output I get when I try to upgrade my software packages:

sudo apt-get upgrade
Reading package lists... Done

Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
E: Unmet dependencies. Try using -f.
sudo apt-get upgrade -f

The problem first showed up trying to upgrade through Ubuntu update manager which recommends trying the -f option from the command line.

Do I need to somehow purge my downloaded but uninstalled packages? Seems like the Linux image file may be bad.

You have scrambled the meta information in /var/lib/dpkg/info. That doesn't sound good.

Check that /var/ isn't filled up by inspecting the output of df.

A way to recover from this situation is to remove the problematic file and reinstall the package afterwards.

cd /var/lib/dpkg/info
mv -f linux-image-3.2.0-32-generic-pae.* /tmp/ 
dpkg -i /var/cache/apt/archives/linux-image-3.2.0-32-generic-pae.deb

With a little bit of luck it was the only scrambled package and you can retry the apt-get install -f.

Thanks a lot that seemed to do it. Your first two commands worked but the last one I couldn't get to work but I managed to do the same thing from synaptic. Now all packages are up to date. – brian Mar 4 '13 at 13:28
@brian If your problem is resolved, don't forget to close this question. – H.-Dirk Schmitt Mar 13 '13 at 12:21
