These instructions have been adapted from the official docs and avoid you have to run any lengthy scripts but you should still be able to get up and running within five minutes or so.

N.B. since the release of 7.5.x and 8.x there are no longer 32 bit releases (so no armhf) but someone noticed that the packages are architechiture neutral (ie. all) in amd64 so you can just pretend to be amd64 on arm64. When doing this, after the update you will still need to do the snappy fix described below.

I am targetting ARM64 but if you are using x86_64 (aka AMD64/amd64) then you should replace all occurances of arm64 (and armhf) with amd64.

Plumb in the Unifi packaging by running:
