pyudev is currently included in test-requirements.txt. Does it need to be in requirements.txt?

Hey Corey,

Yes, it would appear that pyudev is missing in the requirements file for this charm.

[Luciano Lo Giudice (lmlogiudice)]

Strangely, though, it seems that this comes from charms.ceph, which _does_ require pyudev, so this package is somehow not being installed, even though it's a transitional dependency (charms.ceph _is_ a dependency of the dashboard).

[Luciano Lo Giudice (lmlogiudice)]

Update: This only seems to affect jammy-yoga deployments (I've deployed focal-yoga successfully).

After digging around, there's already a patchset for this issue: https://review.opendev.org/c/openstack/charms.ceph/+/851770
