This question already has an answer here:

I'm trying to update from 10.10. This has become a problem for me. After typing

 update-manager -d

I get the following screen.enter image description here

Thereafter I try to update the usual way and get this pair of messages:enter image description here and enter image description here

After the last message, the update process automatically closes.

Can somebody help me either by pointing out what's preventing me from upgrading or how not to update to 11.04 but to 12.04 or 12.10 directly?

This question was marked as an exact duplicate of an existing question.

New questions about end-of-life Ubuntu releases are considered off-topic as per the FAQ. These old releases are unsupported and their use is not recommended. They don't even get updates for newly discovered security vulnerabilities, which makes using them risky. If you install or upgrade to a supported release and this question still applies, please flag and/or comment to request it be reopened. – user25656 Mar 15 '13 at 2:36
@Jorge You can download a new ISO, create a LiveCD or a LiveUSB and install Ubuntu from there. – Lucio Mar 15 '13 at 3:31
@vasa1 I think we should not consider this off-topic, if the goal is to get to a supported release. We support upgrading to non-EoL releases, so we should support updating to an EoL release when it's necessary as an intermediate step for upgrading to a non-EoL release. Presumably this user is using Ubuntu 10.10, also EoL. The only way to upgrade 10.10 to a supported release is through 11.04 (10.10 -> 11.04 -> 11.10). Jorge Campos: Have you enabled the old-releases repositories, as explained here? If it still fails, what happens if you disable extras? – Eliah Kagan Mar 15 '13 at 3:34

It is better for you to upgrade your ubuntu version. Either download a new version iso image and install using it, or run the command

sudo do-release-upgrade

It will automatically upgrade your system by downloading packages.

Actually, it depends on the case. It would be unwise to recommend somebody to upgrade right now from 10.10 to 12.10 because they will face the fact that the following version (11.04 for users with 10.10) is not supported anymore. For that case I would rather tell the user to download the newest ISO and in the live session tell it to upgrade the system. It would save the user a lot of download time and any problem found between version upgrades. – Luis Alvarado Mar 15 '13 at 18:31
Oh! That's the best idea. I didn't think that much. – Yedhu Krishnan Mar 16 '13 at 12:48
