Hi andrewsh, I believe you're aware of the problem, but yesterday's -2
upload does not fix it so I've included full details anyway. Patch is:

    diff --git i/pyproject.toml w/pyproject.toml
    index 8b21bdc8..3c64e248 100644

     # At the time of writing, we only use functions from the version `importlib.metadata`


Since the upload of python-matrix-common 1.2.1 (16th in sid, 22nd in
testing and bullseye-backports) the next matrix-synapse server restart
after upgrading fails to start with the following runtime check:

    Synapse 1.57.1 needs matrix-common~=1.1.0, but got matrix-common==1.2.1

I assume here that the `~=` dep is merely too strict, and note this
isn't an apt error but python module versioning so the package installs
successfully and (see debconf below) doesn't even need a working
homeserver config. The emergency fix to be up and running again was:

    sudo sed -i '/common/s/~=/>=/' /usr/lib/python3/dist-packages/matrix_synapse-1.57.1.dist-info/METADATA

The old synapse version is what Freedombox is on until [#2230] is fixed
and rolled out, but I've checked it still affects the latest upload:

    $ grep common /usr/lib/python3/dist-packages/matrix_synapse-*.dist-info/METADATA
    Requires-Dist: matrix-common (>=1.1.0,<1.2.0)

This has been discussed in [Matrix on Debian], [FreedomBox] and
[Freedombox Dev] channels. I also found upstream has [merged a fix] in
develop, so this patch is only needed until the next version upload.
