summary: Test refreshing snapd and running new units
details: |
Check that snapd can be installed and reverted many times in a row resulting in a
working snapd. Also ensure snapd is working after a reboot.
# UC16 still uses the core snap rather than the snapd snap, so disable this test
# for UC16
systems: [-ubuntu-core-16-*]
environment:
# uploading large snap triggers OOM
SNAPD_NO_MEMORY_LIMIT: 1
restore: |
# Remove all inactive revisions of snapd.
