Comment 18 for bug 1975491

Corey, thank you for looking into it!

I have configured `channel: zed/stable` and left openstack-origin unchanged (it defaults to `distro` and I'm deploying on jammy, so it should mean yoga) for both keystone-saml-mellon and ironic-conductor.

For keystone-saml-mellon it did the job. I was able to successfully deploy the charm.

But the workaround does not work for ironic-conductor. When I run `set-temp-url-secret` action, it fails, and I get the following in the debug-log:

```
$ juju debug-log -i ironic-conductor/0
