Following the update to cdk-addons today, I am seeing:

1.18 is also affected. I'm working on a fix.

Cherry-picked to release-1.17: https://github.com/charmed-kubernetes/cdk-addons/commit/52379bbe369abbcfbf142c046dc26d76e07411b0

The above PR / cherry-pick didn't work out, since we were still pulling in a ceph-mounter config that didn't work with 1.18 and 1.17. We ended up deviating from our normal release process, reverting 1.17/stable and 1.18/stable to earlier, known working snap revs. They are now:

1.17/stable: 4683, 4684, 4685, 4686
1.18/stable: 4715, 4716, 4717, 4718

We have also disabled the build automation until we can ensure this doesn't happen again in the future.
