Ubuntu School – Force Ubuntu Server Upgrade

This may be a bit late for anyone who was experiencing the issue at the time, but here’s how I forced my Ubuntu 11.10 server to upgrade to 12.04 LTS right after 12.04 was released. The normal upgrade process doesn’t work because Ubuntu servers don’t like to upgrade to an LTS release until its first point upgrade.

To upgrade from Ubuntu 11.10 on a server system to Ubuntu 12.04 LTS:

1- install the update-manager-core package if it is not already installed:

sudo apt-get install update-manager-core

2- Edit the release upgrades file

sudo nano /etc/update-manager/release-upgrades and set Prompt=normal;

3- Launch the upgrade tool with the command

sudo do-release-upgrade -d

4- follow the on-screen instructions to complete the upgrade. May take 1hr+ depending on bandwidth, machine specs, installed pkgs

The guts of these instructions were taken from The Unixmen who have a much more detailed tutorial with screenshots on their blog.
