Because Snapd can blow my magic flute, there is just some much wrong with snapd that i COULD write a gist on that. but it would get pretty ranty
First of they ship the new versions of Ubuntu server with LXD and some stuff pre-installed. so first make sure they fuck off by running:
sudo snap remove snap-store
sudo snap remove lxd
sudo snap remove core18
sudo snap remove snapd
On ubuntu 20.04 this cleans itself out when you tell snapd to fuck off. but if you happen to be stuck on 19.04 just go on...
df | grep snap
Output ends with some numbers (eg: 8542), write them down.
sudo umount /snap/core/xxxx
sudo apt purge snapd
