Upgrading Ubuntu 6.06 LTS (dapper) to 6.10 (Edgy)

Despite the GUI nature of the upgrade, it is necessary to begin the update in the terminal.

Unlike the upgrade from Ubuntu 5.10 to 6.06 LTS, the upgrade from 6.06 LTS to 6.10 does not appear in the update manager as a possible update that can quickly be applied using the update manager. This is unfortunately not clearly indicated in a number of the available instructions. Although Ubuntu 7.04 (Feisty Fawn) is already available, it is necessary to go through all the minor steps of upgrading from 5.10 all the way to 7.04. This is the main reason why we are upgrading first to 6.10 'Edgy' as a stepping stone to Feisty Fawn.

To enable an upgrade from Dapper 6.06 to Ubuntu edgy 6.10, we get into the command-line terminal and use the following command

gksu â??update-manager -c -dâ?

This invokes the update manager with the -c and -d switches which direct the update manager to look for updates, and consider pre-release versions of applications.

The command will launch the update manager (Make sure that there are no other open instances of the update manager since only one instance can run at a time), and display a message prompting you to install the 6.10 Edgy upgrade.

Are you looking for a way to upgrade directly from Ubuntu 5.10 or Ubuntu 6.06 to Ubuntu Feisty Fawn 7.04? It is not possible, and you have to upgrade to intermediary versions first...
