There could be a couple reasons for that. Here are some things you can try:

In a Terminal type the following commands:

sudo apt-get autoclean
sudo apt-get clean

then these :

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get update

Finally If none of those get rid of it. I would do this:

sudo apt-get install synaptic

when install go to synaptic and click on edit then fix broken packages. I would like to suggest synaptic for package management anyway.

Let me know how that works out.

When you try this what errors do you get? Just saying it doesn't work does not help much but if you tell us specifically what the errors are we may be able to help. Edit your original question to include what you have tried and the reported errors. – Warren Hill Mar 28 '13 at 11:17

This is a crude answer but it works. Print a list of your installed programs, things you've installed, not a full package list. Backup your /home/ and reinstall.


To get a list of installed packages

dpkg --get-selections > installed-software 

This creates a file installed-software listing the software installed on your computer. You can compare that with the list of files installed by default to find what has been added if you want.

Any version of Ubuntu has a manifest , where all the default pre-installed packages listed.

For 12.04 LTS this list is here =>

Scroll down the page and you will see a file ends with .manifest

Depends on what version of Ubuntu have installed (i386=32bit or amd64=64bit) download the manifest and open it with Libreoffice to read it.
