Slixfeed, which is based on OMEMO, and the installation has failed.
 I have asked him to install python-omemo and he has reported this:

No screenshot arrived here, but this is a pretty typical failure, especially on Windows systems:  pip didn't find a suitable binary wheel package for the Python version / platform combination, and so tried to build one from sources.  That often requires additional setup before it can work.
The question would be why - I looked here:
https://pypi.org/project/XEdDSA/#files
and there are binary wheels for Windows, Linux, Mac for CPython 3.7 through 3.12, and also wheels for PyPy from 3.7 through 3.10, so unless your friend's machine doesn't fit that range, you'd expect that particular package to install okay.
