Upgrade Script Netrunner 17 -> Ubuntu Xenial (16.04 LTS) base

These instructions upgrade Netrunner 17 to the Ubuntu Xenial 16.04 LTS base.

Please use at your own risk and make sure to make a backup of your personal data first before attempting the upgrade.
On a btrfs partition it is highly recommend to create a snapshot of your current filesystem state. You can do so with the command

    sudo btrfs subvolume snapshot / /@_snapshot

To perform the upgrade, open a terminal (yakuake or konsole) and type the following commands:

      wget http://pub.netrunner-os.com/upgrade-17_to_xenial.sh

      chmod a+xr upgrade-17_to_xenial.sh

      sudo ./upgrade-17_to_xenial.sh 2>&1 | tee upgrade.log

During the upgrade, you’ll see a lot of information appear in the terminal and you might see a few warnings/errors. As long as they don’t halt the upgrade, you can ignore them.
If you get asked about restarting services accept it.

The upgrade may take a while (up to 1:30 hours, depending on your machine and you Internet connection), so be prepared for that.

After that you will have a Netrunner 17 running on the Ubuntu Xenial LTS base. Be aware that some packages from Maui 1 will be pulled so the name might appear in some locations.
