Introduction
This upgrade guide will explain how to upgrade an EOL release of Ubuntu to another EOL release of Ubuntu and then get to a supported system. This is meant for systems which cannot install a newer version of update-manager as described in bug 264181 (for link see the See also section). If you want to know what EOL means, have a look overhere: [1] This upgrade exercise has been executed on a fresh install of Ubuntu 6.10 and we will upgrade to 8.04.2 LTS. All the repositories which are on a default installation are enabled, this is the sources.list file which we used to start the upgrade process, all comments have been removed to make it a shorter list.

This guides assumes that the user knows his way on the terminal, as no graphical tools are used.
6.10 to 7.04
- Change all the archive.ubuntu.com (or your countries mirror) URL to old-releases.ubuntu.com
sudo perl -p -i.ORIG -e 's/(?:(?:\w+.)?archive|security).(ubuntu.com)/old-releases.$1/' /etc/apt/sources.list
- Update the package list
sudo aptitude update
- Install update manager
sudo aptitude install update-manager-core update-manager
- Upgrade all current packages
sudo aptitude upgrade
- Upgrade your complete system
You need to run do-release-upgrade once, it will fail, but that doesn't matter. We will trigger the upgrade process from a different executable once we ran do-release-upgrade.
sudo do-release-upgrade
You will now see the following messages on your screen, directly after executing the command:
wesleys@ubuntu-eol-upgrade:~$ sudo do-release-upgrade Checking for a new ubuntu release Done Upgrade tool signature Done Upgrade tool Done downloading extracting '/tmp/tmpH9WhkH/feisty.tar.gz' authenticate '/tmp/tmpH9WhkH/feisty.tar.gz' against '/tmp/tmpH9WhkH/feisty.tar.gz.gpg'
And many more error messages, you can ignore them for now. Remember the directory as seen in the sniplet above. The upgrade process changes old-releases.ubuntu.com links to archive.ubuntu.com, because we upgrade to another EOL release the archive link will not work. To prevent this from happening we are going to patch the upgrade controler script. Contents of the patch file:
--- DistUpgradeControler.py.ORIG 2009-01-29 18:51:43.000000000 +0100
+++ DistUpgradeControler.py 2009-01-29 18:52:44.000000000 +0100

- Apply the patch:
cd /tmp/tmpH9WhkH/ sudo patch < DistUpgradeControler.py.patch # or if you have the patch file in your homedir sudo patch < $HOME/DistUpgradeControler.py.patch
NOTE: If you do not have patch installed run the command below, or make these changes manually. You will need root privileges to edit the file (as you can see from the sudo patch line).
sudo aptitude install patch
When you have applied the patch execute the following command:
sudo ./feisty --frontend DistUpgradeViewText --mode=server
Now reboot your machine. When your machine comes back up again you are running feisty. You can check this by running
lsb_release -a
7.04 to 7.10
This upgrade did not go as smooth as I expected. I expected the upgrade process to be similar to 6.10 -> 7.04 like in bug 264181, but that was not the case.
- Run do-release-upgrade
sudo do-release-upgrade
It will fail, because it does not rewrite old-releases.ubuntu.com to archive.ubuntu.com as expected. But we need to run it once, to get some files from the feisty repo's. Make sure you remember that /tmp directory again, we are going to need it in a sec. If you did not record the location we can find it pretty easy:
find /tmp -name gutsy
This will tell you where the upgrade script resides and you just need to enter that directory.
- Change your sources.list
We now need to change our sources.list to have only gutsy (7.10) repositories, you may wish to use a different mirror (archive then becomes in my case nl.archive).
sudo perl -p -i.feisty -e 's/old-releases.ubuntu.com/archive.ubuntu.com/g' /etc/apt/sources.list
If you have the security repositories make sure you change them to security.ubuntu.com, eg
deb http://archive.ubuntu.com/ubuntu feisty-security main restricted # Changes to deb http://security.ubuntu.com/ubuntu feisty-security main restricted
Once this is done we are going to change feisty to gutsy:
sudo perl -p -i -e 's/feisty/gutsy/g' /etc/apt/sources.list
Some users have mailed me that there are some extra steps to complete the upgrade. We need to edit the prerequists-sources.list in the /tmp directory to make sure the release-upgrader-dpkg and release-upgrader-apt packages can be installed.
cd /tmp/tmpeBHg_m
perl -p -i.feisty -e 's/(http:\/\/).*archive(.ubuntu.com)/${1}old-releases$2/' prerequists-sources.list
Or make the changes manually:
deb http://${countrymirror}archive.ubuntu.com/ubuntu feisty-backports main/debian-installer
to
deb http://old-releases.ubuntu.com/ubuntu feisty-backports main/debian-installer
- Continue the upgrade process
cd /tmp/tmpeBHg_m sudo ./gutsy --frontend DistUpgradeViewText --mode=server
Now reboot your machine. When your machine comes back up again you are running gutsy. You can check this by running
lsb_release -a
7.10 to 8.04.2
Please have a look at the following documentation: https://help.ubuntu.com/community/HardyUpgrades But in short:
sudo do-release-upgrade
Reboot and you are good to go.
