[Bug 2080208] Re: ceph-volume AttributeError EntryPoints

[Rgpublic]

I can also confirm the new packages works. If you are on the caracal
PPA, have upgraded and got a broken OSD due and a non-working ceph-
volume, I got out of this by running:

* sudo add-apt-repository ppa:james-page/dalmation
* Deleting the caracal file from /etc/apt/source.list.d
* apt dist-upgrade
* ceph-volume lvm activate --all

Hope this helps others. I haven't understood what the caracal/dalmation
distinction is all about tbh, but it seems "dalmation" has newer
packages (from September 12th) and these packages have working ceph-
volume and working OSDs.

It's all a bit confusing. I wonder if/when we'll a get a completely
working Ceph version in the normal repo without any PPA... Does anyone
know whether this is planned? And another thing I'm asking myself: How
will we be able to switch back if it arrives? Just by removing the PPA
and running apt dist-upgrade?

Title:
  ceph-volume AttributeError EntryPoints

Status in Ceph:
  Unknown
Status in ceph package in Ubuntu:
  Fix Released
Status in ceph source package in Noble:
  Triaged
Status in ceph source package in Oracular:
  Fix Released

Bug description:
  [Impact]
  ceph-volume tool is non-functional in proposed updates for Ubuntu 24.04 (19.2.0~rc2-0ubuntu0.24.04.1).

  
  [Test Case]
  sudo apt install ceph-volume
  sudo ceph-volume -h

  
  [Where things could go wrong]
  The upstream proposed fix has not yet been accepted and the patch does increase the code complexity in this area; fix has been tested in PPA prior to upload to reduce risk.

  
  [Original Bug Report]
  ceph-volume fails with an AttributeError, cf. below.

  I believe this might be due to importlib_metadata removing deprecated
  shims:
