Ubuntu: Problem upgrading from Jaunty to Karmic

Solution 1:

Solved it. Turns out that /etc/update-manager/meta-release is pointing to http://changelogs.ubuntu.com/meta-release and that file says:

Dist: karmic
Name: Karmic Koala
Version: 9.10
Date: Thu, 29 Oct 2009 12:00:00 UTC
Supported: 0
Description: This is the 9.10 release
Release-File: http://archive.ubuntu.com/ubuntu/dists/karmic/Release
ReleaseNotes: http://changelogs.ubuntu.com/EOLReleaseAnnouncement
UpgradeTool: http://archive.ubuntu.com/ubuntu/dists/karmic-proposed/main/dist-upgrader-all/0.126.9/karmic.tar.gz
UpgradeToolSignature: http://archive.ubuntu.com/ubuntu/dists/karmic-proposed/main/dist-upgrader-all/0.126.9/karmic.tar.gz.gpg

I downloaded the file, changed "Supported: 0" to "Supported: 1" and hosted the file on my own webserver and pointed the meta-release to my server instead. Worked perfectly.

Don't know if there is a reason Ubuntu wants to make it impossible to do this upgrade or if accidentally changed supported to 0.

Solution 2:

Another solution:

mkdir -pv /tmp/karmic
cd /tmp/karmic
wget http://old-releases.ubuntu.com/ubuntu/dists/karmic-proposed/main/dist-upgrader-all/0.126.9/karmic.tar.gz
tar zxvf karmic.tar.gz
./karmic

reboot and then:
