====== Ubuntu Release Upgrades ======

  * [[Ubuntu]]

Install upgrade software:

<code>
aptitude install update-manager-core 
</code>

Set the preferences for release upgrades in ''/etc/update-manager/release-upgrades'' and set the prompt to ''never'', ''lts'' or ''normal''

Start the release upgrade:

<code>
do-release-upgrade -d
</code>

This will open an SSH service on port 1022 to gain access.  Add a rule to your firewall first to make sure you can get in.
