If your metadata.yaml lists any resources: Those did not get packed with charmcraft pack, so they didn’t get uploaded with charmcraft upload <charm> either. Make sure to upload them as well! See more: How to publish a resource on Charmhub.

Every time a new binary is uploaded for a charm, a new revision is created on Charmhub. We can verify its current status easily by running charmcraft revisions <charm-name>. See more: charmcraft revisions.

Release the charm

Finally, release your charm into a channel so it can become available for downloading:

$ charmcraft release my-awesome-charm --revision=1 --channel=beta

Uploaded charms are not automatically released and made available for download. To consume a charm, first release it into a channel (any channel). Then Charmhub will display the charm’s information at charmhub.io/<charm-name>. (The default information displayed is obtained from the most stable channel.)

Just in case, also check your charm’s status:

$ charmcraft status my-awesome-charm
Track    Channel    Version    Revision
latest   stable     -          -
         candidate  -          -
