<Markuze> Hi, folks.
On ubuntu 24.04 im building ceph.
All submodules and dependencies are in place.
But I keep getting this error on MDS :

<Venky Shankar> I'm checking <https://github.com/PyO3/pyo3/issues/576> and it looks like some recent versions of PyO3 support sub-interpreter (which is heavily used in ceph-mgr).

<gregsfortytwo> Who added PyO3? If it doesn’t work in 24.04 either they have an easy workaround, or they messed up…

2024-11-11T13:50:07.320Z

<Venky Shankar> checked git history and nothing related to PyO3 was added...

<gregsfortytwo> Ugh, not merged but see [https://github.com/ceph/ceph/pull/57926](https://github.com/ceph/ceph/pull/57926)

<gregsfortytwo> If it is impacting all modules and not just the dashboard, something happened to make it implicitly rely on their dependencies. Maybe the API work they’ve been doing!

<Markuze> my current working theory is that the root cause is that the default python version has changed from 3.10 to 3.12.
I’m already working in Pyenv, which helped solve the issues I was initially seeing with missing dependencies.

<Venky Shankar> @Markuze mentioned in standup that he's using Py 3.12 and that's probably one of the reasons..

2024-11-11T14:04:22.363Z

<Markuze> I will try venv.

<Markuze> I know @Igor Golikov also is using a Ubuntu24.04 but his default python3 is 3.10.
