When upgrading an Ubuntu server to 8.04 LTS, you should use the new and improved server upgrade system. Use the following steps to activate this upgrade process:
- Enable the “dapper-updates” repository
- Install the “update-manager-core” package. Dependencies include python-apt, python-gnupginterface and python2.4-apt.
- Run the command “sudo do-release-upgrade” in a terminal window
- Follow the prompts on-screen.
