11.10 to 12.04 (Oneiric to Precise)

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/ oneiric main restricted universe multiverse
     deb http://old-releases.ubuntu.com/ubuntu/ oneiric-updates main restricted universe multiverse
     deb http://old-releases.ubuntu.com/ubuntu/ oneiric-security 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
     sudo aptitude update && sudo aptitude safe-upgrade
  • Perform the release upgrade.
     sudo do-release-upgrade
  • Check your new version

    Reboot your machine and you can now run lsb_release -a to check the new version of Ubuntu.
