Comment 10 for bug 1669306

I didn't read `confinement: classic` before, this changes everything. The behavior of `classic` is marked as experimental to give us some space to allow changes until we find a common denominator that works for all projects.

If `command` in `prime/meta/snap.yaml` for the `apps` entry doesn't start with <path>/python3 I suspect something is going wrong (and we can fix that if python3 is indeed in prime). In the meantime, does changing command to:

`command: $SNAP/usr/bin/python3 $SNAP/bin/juju-act`

solve the running problem?
