7.4 SNAP Problem Solving

Cloud servers as virtual machines running on top of real machines seem to have an incorrect setup for snaps creating a scope within the virtual environment within which they are expecting to run:

$ firefox
/user.slice/user-1000.slice/session-818.scope is not a snap cgroup

The solution is to “correct” one environment variable, DBUS_SESSION_BUS_ADDRESS:


Set it as below and all is good:


Then start the snap installed app (firefox in this case).

sudo snap remove –purge

Generate a list of installed snaps:

snap list | awk 'NR > 1 {print $1}'
