1. title Upgrading Dapper to Hardy

<< < Breezy Edgy >>

6.06 to 8.04 (Dapper to Hardy)

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. Note:: Ubuntu 6.06's support has ended in June 2009 for desktops and will end June 2011 for servers. This will mean a lot of desktop applications are not supported/updated anymore. See this list of supported packages. Upgrading 6.06.x to 8.04 is regarded as a regular upgrade. Please see DapperUpgrades or HardyUpgrades for more information.

Requirements

• /etc/apt/sources.list

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

You can make use of -backports, -proposed repositories if you want. For more information about repositories see Repositories/Ubuntu.

The upgrade

• 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

• 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!

• Run the update script

sudo do-release-upgrade

• Important note: you may need to edit the file /etc/fstab to change "hda" old IDE disk notation by "sda" new disk notation.
• Check your new version

Reboot your machine and you can now run `lsb_release -a` to check the new version of Ubuntu. << < Breezy Edgy >>
