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 That URL ceased to resolve (superseded by instructions at zerovm.org/download.htm), so apt-get would always end up tripping over that.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. – Digital Trauma Apr 7 '14 at 16:27
  • I had this problem with 17.04, upgrading to 17.10 solved the problem – jim smith Apr 13 '18 at 11:07

Try cleaning up your apt-cache and running any updates

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 or Software Updater, then click Settings > Ubuntu Software tab, then select Other from the Download From menu 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 '16 at 5:13

    I tried this on Ubuntu netbook edition (10.10). When I tell it to Select Best Server, it goes through all 361 of them and then concludes, "No suitable download server was found. Please check your Internet connection." Yet, I can access the internet just fine. – Brad Turek Oct 18 '18 at 20:57

"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 -> Software & Updates -> Other Software -> Click on offending entry and hit Remove (OR simply un-check so its ignored yet visible for later)

    Note this can also apply if "cdrom" is in the repo list, see askubuntu.com/a/386048/254 – matt wilkie Jan 28 '16 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 '16 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 '16 at 1:16
  • That was it, "cdrom" was the offender (I'm running a virtual machine), unchecked it and the problem went away – rboy Sep 15 '17 at 3:45

Assure cdrom is unchecked then 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.
