Whenever I try to install anything with the Ubuntu Software Center, the following error appears.

Failed to download repository information

Check your Internet connection.

E:Unable to parse package file /var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise_multiverse_i18n_Index (1)

The above does not work for me. I notice when running "apt-get update" the concatenated string contains the IP for this device (in my case, NOT the nameserver ( It is then unable to connect. –  user94170 Oct 2 '12 at 23:16
I'd like to add this as an answer to this protected question, but don't have the rep here yet. Anyway, I ran into this problem. In my case I had forgotten I had added a file to /etc/apt/sources.list.d/ for a 3rd party package from https://z.litestack.com/v1/repo/ubuntu/. That URL ceased to resolve (superseded by instructions at zerovm.org/download.htm), so apt-get would always end up tripping over that. sudo rm /etc/apt/sources.list.d/zerovm-precise.list fixed it for me. –  DigitalTrauma Apr 7 '14 at 16:27

Try cleaning up your apt-cache and running any udpates

sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

If you still have issues, then change your repo mirror: Open "Update Manager", then click "Settings" -> "Ubuntu Software" tab, then select "Other.." from the "Download From" and click the "Select Best Server" button. Now try updating/upgrading again.

"Software Updater" will give same error message for issues like :

W: Failed to fetch http://ppa.launchpad.net/crass/ufraw/ubuntu/dists/raring/main/binary-amd64/Packages 404 Not Found

Solution : Settings -> Other Software -> click on offending entry and hit Remove

cut and paste entire set of below commands :

sudo apt-get clean ;
cd /var/lib/apt ;
sudo mv lists lists.old_`date '+%Y%m%d_%H%M%S'`   ;
sudo mkdir -p lists/partial ;
sudo apt-get clean ;
sudo apt-get update

The semicolon demarcates each command so they can be pasted together.

there is something that worked for me:

please goto update manager settings > under Ubuntu software tab uncheck "cdrom with Ubuntu 12.04 'precise pangolin'"

then under other softwares tab uncheck first three options which are cdrom with Ubuntu 11.04 and 12.04 and etc.
