I have an environment with the same behavior in a Bionic VM that does not use charm.
Preparing to unpack .../pacemaker_1.1.18-0ubuntu1.3_amd64.deb ... Unpacking pacemaker (1.1.18-0ubuntu1.3) over (1.1.18-0ubuntu1.1) ... Log ended: 2020-11-11 06:54:05
After the upgrade, there was an IP(master/vip) switch between the nodes that left the environment unavailable.
