10.04 -> 12.04 Upgrade . Server. do-release-upgrade fail. What sources to change

Question

I am current trying to upgrade a ubuntu server via ssh. I am stuck since i can not perform a do-release-upgrade. It tries maverick instead of trying 12.04

Essentially I think he is failing because 12.04 is an old release. I had to change /var/lib/update-manager/meta-release to start using old-releases mirrors instead of archive since it was failing before with another problem.

My sources : http://pastebin.com/xrFTaKjn My /var/lib/update-manager/meta-release : http://pastebin.com/A3Zs6DYx

What is wrong?

My error:

Checking for a new ubuntu release Done Upgrade tool signature Done Upgrade tool Done downloading             authenticate 'maverick.tar.gz' against 'maverick.tar.gz.gpg'  extracting 'maverick.tar.gz' tar: Removing leading `/' from member names

It fails because you are on 10.10 (Maverick) and not 10.04 (Lucid). Upgrading from 10.10 to 12.04 is unsupported, while 10.04 -> 12.04 should work.

10.10 is no longer supported, and there is no upgrade path to any supported currently release. Just backup, and reinstall.

12.04 will be supported until Aprl 2015.

To upgrade from 10.04 server to the next LTS, install update-manager-core,
then edit /etc/update-manager/release-upgrades, and set Prompt=lts.

You'll obviously have to edit the /etc/apt/sources.list and reset every line back to lucid first.
