Charm upgrade from rev 108 to 166 fails

[cbartz]

Bug Description

I am not able to upgrade an already related grafana-agent on arm substrate from rev 108 to 166 . It goes into error state with a failed upgrade-charm hook:

foo@bar:~$ juju status

The same applies when upgrading to rev 164 (amd arch).
