The problem is still ongoing on 20.04. I have to open the console daily
and run the following commands, due to snapd starts to use my SSD non-
stop when I restart. This is faking as `updating Chromium`.
sudo kill -9 $ (pgrep -fn snapd)
sudo systemctl stop snapd
sudo systemctl stop snapd.socket
sudo systemctl stop snapd.service
snap changes

Reading from the `/var/lib/snapd/assertions/...` files, it's just a
"device-key".
Writing to `/var/lib/snapd/state.json` and 2 files with subnames like
`state.json.gTFjQFf8Kpps` it is fake. It writing each second and change only
the timestamp string in the files.
No any traffic recieving from net.
