Comment 15 for bug 2039604

I recently observed similar issues during an upgrade from focal/ussuri to focal/wallaby, with these charms: ceph-mon, aodh, barbican, ceph-radosgw, designate, placement, octavia.

The symptoms varied, but all seem related:

- ceph-mon: no units wrote the updated cloud-archive ppa (cloud-archive.list still contained the line for victoria)

- aodh: all units wrote the updated cloud-archive ppa, but only 2 out of 3 upgraded the aodh packages. aodh/0 still had aodh v11.0.0 installed, and apt was showing v12.0.0 was available (eg. ppa added successfully, apt update run, but not apt upgrade)

- barbican: all units wrote the updated cloud-archive ppa, but no units upgraded the barbican packages.

- ceph-radosgw: no units wrote the updated cloud-archive ppa

- designate: all units wrote the updated cloud-archive ppa, but only 2 out of 3 upgraded the designate packages. designate/0 was not upgraded.

- placement: all units wrote the updated cloud-archive ppa, but only 2 out of 3 upgraded the designate packages. placement/0 was not upgraded.

- octavia: all units wrote the updated cloud-archive ppa, but no units upgraded the octavia packages.
