While investigating this issue I also found out that the validation on the charm name in the libs, is in contradiction with what the charmhub API expects.

If I put the following in my charmcraft.yaml

charm-libs:
  - lib: traefik-k8s.ingress
    version: "2"

I get the following error:

- Invalid charm name in lib 'traefik-k8s.ingress'. Try replacing hyphens ('-') with underscores ('_'). (in field 'charm-libs[0].lib')

But if I use underscore instead the charmhub API doesn't recognize the charm-name

❯ curl -X POST 'https://api.charmhub.io/v1/charm/libraries/bulk' -H "Content-Type: application/json" --data '[{"charm-name": "traefik_k8s", "library-name": "ingress", "api": 2}]'
{"error-list":[{"code":null,"message":"Items need to include 'library_id' or 'package_id'"}]}

While using an hyphen:

❯ curl -X POST 'https://api.charmhub.io/v1/charm/libraries/bulk' -H "Content-Type: application/json" --data '[{"charm-name": "traefik-k8s", "library-name": "ingress", "api": 2}]'
