Title: python-enum34 not installed on charm upgrade Status in Nagios Charm: New Bug description: Commit b825a12877ce80aad6325f95f2c08948728dabbf updated charmhelpers, and added a dependency to python-enum34 (the backport of the Enum class for python 2). This packages in installed as part of the execution of hooks/install, but not during charm upgrade. Upgrading from an earlier nagios charm version to 20.08 will therefore fail with DEBUG unit.nagios/0.upgrade-charm ImportError: No module named enum ERROR juju.worker.uniter.operation hook "upgrade-charm" failed: exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/charm-nagios/+bug/1893434/+subscriptions -- Mailing list: https://launchpad.net/~nagios-charmers Post to : [email protected] Unsubscribe : https://launchpad.net/~nagios-charmers More help : https://help.launchpad.net/ListHelp
