Description

Older Juju used "series" like "focal"
New Juju uses "bases" like "[email protected]"

It would save from a weird workaround

Need to decide how we do this:

  • drop Juju 3.2 support and move all code to bases?
  • or dual-wield series and bases depending on juju controller version?

For 3.x series of this library, we have to make a table of series --> bases, like "focal" -> [email protected]

For 4.x series, we could force all users to upgrade, maybe?

I think this is reasonable -- drop series entirely and only use bases in python-libjuju targeting Juju 4.0.

If no users are requesting support for bases, do we need to support them in 3.x of this library? I know that we probably should, but for example Juju 3.6 seems to still supports Charms facade version 6, which still uses series instead of bases.

test: bump series and pin revision for local charm refresh tests
19381a8 
A recent update to the 'ubuntu' charm requires the use of the v2
metadata format when refreshing from a local charm. The v2 format
replaces series with bases, among other changes. Properly supporting
this will need to wait on updating python-libjuju to handle bases as
well as (or instead of) series -- see issue juju#1156.

In the meantime, fix the test breakage by pinning the install of
'ubuntu' in broken tests to the previous revision (24). This revision
has a mismatch with the specification of the "focal" series (20.04), so
also bump the series in the local charm to "jammy".
