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I had forgotten I had added a file to /etc/apt/sources.list.d/ for a 3rd party package from That URL ceased to resolve (superseded by instructions at, so apt-get would always end up tripping over that. sudo rm /etc/apt/sources.list.d/zerovm-precise.list fixed it for me. – Digital Trauma 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.

You rock! This fixed my VMware Ubuntu! I was kind of freaking out that I'll have to re-install it but this worked great. – Georgi Angelov Mar 3 at 5:13

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

W: Failed to fetch 404 Not Found

Solution : Settings -> Other Software -> click on offending entry and hit Remove (OR simply un-check so its ignored yet visible for later)

Thanks, this was my issue. It was a third-party repo. – Jeremy Sep 14 '15 at 14:41
Note this can also apply if "cdrom" is in the repo list, see – matt wilkie Jan 28 at 20:17
This is the correct answer; the problem is that the error message does not indicate which entry is the offending one. :( But yes, once you can figure that out, works like a charm! – Bane Mar 9 at 16:02
Worked for me, too. I ran into this problem when I installed the blueman and bluez5 packages to support my Microsoft BT mouse. Clearing the checkboxes next to these packages on the "Other Software" tab in Software & Update fixed it. – Nicole Hamilton Jul 17 at 1:16

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

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.
