Cannot deploy local charm due to `eries "jammy" not supported by charm, the charm supported series are: focal`

[Gary.Wang]

All of a sudden, we hit the following error in the CI when deploying a bundle with a set of local charms
```
05:03:57 - deploy application anbox-stream-agent on jammy
05:03:57 - upload charm /home/ubuntu/src/tests/spread/data/anbox-cloud_1.22.0-alpha.595+git996b4482/charms/jammy/anbox-stream-gateway_1.22.0-alpha.595+git996b4482_jammy.charm for series jammy with architecture=arm64
05:03:57 ERROR cannot deploy bundle: cannot deploy local charm at "/home/ubuntu/src/tests/spread/data/anbox-cloud_1.22.0-alpha.595+git996b4482/charms/jammy/anbox-stream-gateway_1.22.0-alpha.595+git996b4482_jammy.charm": series "jammy" not supported by charm, the charm supported series are: focal
```

This charm does support the jammy series as declared in the metadata.yaml file
```
name: anbox-stream-gateway
...
...
series:
  - focal
  - jammy
```

The above issue began occurring following the release of a new revision of juju on the 3.1/stable channel
```
  3.1/stable: 3.1.8 2024-04-12 (26977) 95MB -
```

Any hints/suggestions/workaround so far for the above issue?
Thanks

Defining series in metadata.yaml is deprecated but I wouldn't expect Juju 3.1 to break.

Moving forward, the supported series will become supported bases and these will be read from the charm's manifest.yaml file.

I wonder if a patch in this area accidentally landed in 3.1.

The manifest will be preferred if present. Does it have an entry for a 22.04 base?

[Gary.Wang (gary-wzl77)]

Yes, it does.
From what I've seen
```
$ cat manifest.yaml
