I have now (erroneously) reported two bugs against juju, which were actually bugs against charms. (e.g. Bug #1912644 “AttributeError: module 'platform' has no attribute...” : Bugs : juju and Bug #1914415 “Potential race condition leads to broken applicati...” : Bugs : juju)
Is there an easy way to file bugs against charms, so that the charm authors will take notice?
Looking at the Charmhub entry for one of the charms (e.g. Deploy Postgresql K8S using Charmhub - The Open Operator Collection), there’s no clear way to contact the author, or visit the GitHub repo or web site of the charm’s source.
