During April we will be upgrading Abisko from Ubuntu Precise to Ubuntu Xenial.
This upgrade will make the environment on Abisko match the one already in use on Kebnekaise.
The reason for doing this is that Ubuntu Precise has End-of-Life on 2017-04-28. (End-of-Life means that after that it will no longer get security updates, bug fixes, etc.)
For more information on the upgrade please see the Abisko: Precise to Xenial migration page.
