Attempting to delete any of my collections on the public Ansible Galaxy website fails. For example, when trying to delete the collection [mwadman/dnsmasq\_roles](https://galaxy.ansible.com/ui/repo/published/mwadman/dnsmasq_roles/).  
I’ve checked that none of the collections that I’m trying to delete are dependencies of other collections.

The deletion fails silently without providing a user-facing error message or description in the web UI. I had to navigate to task management to determine it had failed.

See [screenshot here](https://imgur.com/a/iNuk9Oo) for details.  
Traceback pasted here if that’s useful:

          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

```

Please let me know if there’s something I need to do to be able to delete collections.

I’m not sure if it’s possible. This comment was made a few years ago but reflects my current understanding [Deleting/disabling ansible galaxy collection - #5 by sivel](https://forum.ansible.com/t/deleting-disabling-ansible-galaxy-collection/38271/5).

As a workaround you could publish an empty version and delete everything else. It’s still there but does nothing.
