- title Upgrading Breezy to Dapper
5.10 to 6.06 (Breezy to Dapper)
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.
- Make sure your sources.list is correct
For the upgrade you only need this list, comment your original sources or remove them.
# Required deb http://old-releases.ubuntu.com/ubuntu/ breezy main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ breezy-updates main restricted universe multiverse deb http://old-releases.ubuntu.com/ubuntu/ breezy-security main restricted universe multiverse # Optional #deb http://old-releases.ubuntu.com/ubuntu/ breezy-backports main restricted universe multiverse #deb http://old-releases.ubuntu.com/ubuntu/ breezy-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 installed packages
sudo aptitude update && sudo aptitude upgrade
If packages were held back you may want to run:
sudo aptitude dist-upgrade
- If you run a -desktop version of ubuntu, please reinstall this package:
sudo aptitude reinstall ubuntu-desktop # or kubuntu, xubuntu, edubuntu, etc
NOTE: It could be that you just upgraded your kernel, if this is the case, please reboot!
- Change your repositories
Please make sure you have the following sources.list:
# Required deb http://archive.ubuntu.com/ubuntu/ dapper main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ dapper-updates main restricted universe multiverse deb http://security.ubuntu.com/ubuntu/ dapper-security main restricted universe multiverse # Optional #deb http://archive.ubuntu.com/ubuntu/ dapper-backports main restricted universe multiverse #deb http://archive.ubuntu.com/ubuntu/ dapper-proposed main restricted universe multiverse
- Update the package list and perform a dist-upgrade
sudo aptitude update && sudo aptitude dist-upgrade
- Check your new version
Reboot your machine and you can now run `lsb_release -a` to check the new version of Ubuntu.
- Remove obsolete packages
Now you will enter aptitude in interactive mode, select Obsolete and locally installed packages menu and press '_', then press 'g'. It could be that you will get messages that aptitude wants to remove your current kernel, do NOT remove it, leave it, we can remove it later on. << < Hoary Dapper >>
