Hi, thanks for the report!

I can't reproduce the issue with microceph (I would guess a re-run would have it working, or at the worst case a charmcraft clean followed by re-running), but the second item is fixed by canonical/craft-providers#722. I've made a local snap build that bumps craft-providers and makes it work, so I'll put that out on the candidate channel ASAP.

If you still face issues with the microceph charm after cleaning,, please chat with us on Matrix or open a new issue.

Ah, I find out the microceph issue is relate to my environment have docker installed. Uninstall docker and restart fix the issue.

Sorry for cause distress and thanks for quick response on this!!
