Hi everyone,

python-matrix-nio-0.20.0 cannot currently be build:

#+begin_src 
building /gnu/store/lnyrxhl8h2mcyxjgkwhn52vpckp9bpy2-python-matrix-nio-0.20.0.drv...
- 'sanity-check' phasebuilder for `/gnu/store/lnyrxhl8h2mcyxjgkwhn52vpckp9bpy2-python-matrix-nio-0.20.0.drv' failed with exit code 1
build of /gnu/store/lnyrxhl8h2mcyxjgkwhn52vpckp9bpy2-python-matrix-nio-0.20.0.drv failed 
#+end_src

On a first glance and according to the build log this is because a
version of python-h11 between 12.0 and 13.0 is expected; but Guix only offers
python-h11 v14.0.0:

#+begin_src 
starting phase `sanity-check'

A possible solution could be to define a package variant of python-h11
as python-h11-13.0 and let matrix-nio depend on that in
the propagated-inputs of matrix-nio.

I haven't had the time to investigate this any further, but I'll at
least try to further look into this/maybe try to work on a patch myself
(I have only recently started using Guix, so getting to a set-up where I
can hack on guix packages may need some time still).

Regards,

Wilko Meyer
