I continuously failed to upgrade my Ubuntu from 11.04 to 12.04.

I tried running these commands:

  • sudo apt-get upgrade
  • sudo apt-get update
  • do-release-upgrade

But none of them work.

The error they give is usually one of these:

  • failed to fetch ...
  • Some index files failed to download. They have been ignored, or old ones used instead.
  • Some third party entries in your sources.list were disabled. You can re-enable them after the upgrade with the 'software-properties' tool or your package manager.

I searched from this site, and just that it could be coming from update server. People recommended to edit in Ubuntu Software Center, from "main server" to "best server" or "server of US'... But I can't find these options in my software center.

But my Ubuntu Software Center is not providing any menus like that, instead, it seems like just download center like App store of mac.

How can I change the download server for update of my machine?

ps) sudo update-manager gives following error

Please somebody help me :(

  • @mikewhatever, He's apparently trying to upgrade from 11.04 to 12.04, so the issues that he's having are irrelevant to what he wants to do. I don't think it's a duplicate of that question, however, the first answer might help what he's trying to do (if the update manager is being particularity annoying) – MiJyn Apr 08 '13 at 02:12
