[PVE-User] Cant connect to ceph anymore

[proxmox at elchaka.de]

So, a "bit" late... i know - but to complete this thread as "solved":

I have resolved the issue a few months ago with

Aptitude install ceph

This has found few depenedencies and resolved by himself.

It is now working since then without any issues
