I'm using ubuntu 11.10 and in the update manager I have a message that says package information last updated 59 days ago press the check button to check for software updates

I do that, but i'm up to date. I checked other threads with this same problem, and saw i should do sudo apt-get update in a terminal to see which repository is not up to date and when I did, I got this message:

Failed to fetch http://extras.ubuntu.com/ubuntu/dists/oneiric/Release

Then I checked for this repository in software sources but couldn't find this specific one. In my /etc/apt/sources.list.d I have only one line:

deb http://archive.canonical.com/ubuntu oneiric partner #Added by software-center

So now I don't know what to do more. Should I upgrade to 12.04 and will it solve my problem? I wouldn't want to upgrade if there is a problem in the last version but I don't know much about Ubuntu so, can anyone help me please?

Thank you!!


Make a backup of your sources file before editing it.

sudo cp /etc/apt/sources.list /etc/sources.list.bak

Next, run this command to remove the offending line:

sudo su -c "cat /etc/apt/sources.list.bak | grep -v 'extras.ubuntu' > /etc/sources.list"

Be sure not to make any typos.

  • i think it should be /etc/apt/source.list. – atenz Jul 6 '12 at 17:43

I finally found the answer. Software updates/other/ uncheck the checkmarks from the top three - in my case that was CD and unsupported. Then I ran a check again, and voila! Software up to date. Previously it kept saying 97 days ago etc. (today it said 99 days).

P.S. I got the answer from a forum for Ubuntu 13.04, which I do not have (I'm running 12.04). Here's the link:
