Upgrade to Humble + Garden

[Louise Poubel]

The main goal is to get added mass support.

Garden is currently unstable and will be officially released in the end of September.

Humble's official pairing is Fortress, so we'll still be using a non-official combination.

Fix Garden to run from Debians:
