6.10 to 7.04 (Edgy to Feisty)
Before you start
Please make sure you've read and understood the main EOLUpgrade page.
I would recommend using clonezilla for backing up your current installation. It is very easy to backup and restore your partitions with clonezilla. It takes less then 30 minutes to backup/restore a 20Gb root filesystem which has 4-5 Gb used space.
Please make sure you have the following sources.list.
## EOL upgrade sources.list # Required deb http://old-releases.ubuntu.com/ubuntu/ edgy main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ edgy-updates main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ edgy-security main restricted universe multiverse # Optional #deb http://old-releases.ubuntu.com/ubuntu/ edgy-backports main restricted universe multiverse
You can make use of -backports, -proposed repositories if you want. For more information about repositories see Repositories/Ubuntu.
- Make sure your sources.list is correct (see requirements)
- Update the package list and get fully upgrade all packages
sudo aptitude update && sudo aptitude upgrade
NOTE: It could be that you just upgraded your kernel, if this is the case, please reboot!
- 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.
You will now see the following messages on your screen, directly after executing the command:
$ 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 (/tmp/tmpH9WhkH/). 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 fix the upgrade controler script.
I use vi as an editor, you can use your editor of choice, nano, gedit, etc.
