I installed recently in my personal computer 12.04.

When a try to install some software (Dropbox or Chromium per example) from the Ubuntu software Center or when I try to install some package using the terminal (sudo apt-get install guake for example), I find an issue. There is some problem with the packages list.

What I can do? I tried to run sudo apt-get update, but the issue persist.

First make sure your Internet connection works. Then enter the following commands one by one, in terminal.

sudo apt-get clean
sudo apt-get update
sudo apt-get -f install

If that didn't work,

Go to

Edit > Software Sources in Software Center.

Set "Main Server" in "Download From" drop down menu.

Then run sudo apt-get update in terminal again.

Hmm, we could really use a 'aptgetsane' script to triage issues like this. We basically have no idea how many PPAs are installed or what state the packaging is in. It would be neat to revert to installation defaults, while saving all the original settings, to diagnose said issues. –  ppetraki Oct 3 '12 at 15:44
