8.10 to 9.04 (Intrepid to Jaunty)
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.
The upgrade
- Please make sure you have the following sources.list (/etc/apt/sources.list).
## EOL upgrade sources.list # Required deb http://old-releases.ubuntu.com/ubuntu/ intrepid main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ intrepid-updates main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ intrepid-security main restricted universe multiverse # Optional #deb http://old-releases.ubuntu.com/ubuntu/ intrepid-backports main restricted universe multiverse #deb http://old-releases.ubuntu.com/ubuntu/ intrepid-proposed main restricted universe multiverse
You can make use of -backports, -proposed repositories if you want.For more information about repositories see Repositories/Ubuntu.
- Update the package list and upgrade all the installed packages
