Public bug reported:
I am doing series upgrade on charmed openstack following the normal
procedure. The upgrade is cloud:bionic-ussuri to focal distro.
On compute units I notice that running apt full-upgrade prior to doing
do-release-upgrade results in incorrect file permissions on
/var/lib/nova/.ssh/. This in turn breaks migrations at least.
I did not catch if it was nova-common or nova-compute that did this
during the upgrade, but something wrote 644 on everything.
