Hi Norbert,Because of your bug report, it made me try a backport of Ceph to Bullseye. And I couldn't experience what you had. For me, ceph-mgr started with no issue. But I wasn't doing an upgrade, this was a fresh install.
Could you explain the steps you made to get to the state you described? I'll soon try an upgrade procedure as well, and see how it goes. Cheers, Thomas Goirand (zigo)
