Ouch. There's an AUR package for that but it hasn't been updated since
2015 and the most glaring issue is that it currently depends on
"twisted" which was deprecated for "python2-twisted" a long time ago.

Also yeah, it imports wormhole in the python code, and uses python2, so
it should be updated to new versions of tahoe-lafs and in the process
updated to depend on python2-magic-wormhole.

If you're interested in this package, please request it to be orphaned,
then fix it up.

The python3 version is in the official repos.

The Makefile that is being run over there unconditionally uses the
command "sphinx-build" which is provided by python-sphinx, and the
package needs to be updated to depend on that instead... or to stop
using the Makefile, and invoke sphinx-build2 instead.

Python2 is not going away IMHO. There is too much code which still uses it.

The Python Software Foundation may drop support for it, but I suspect
other interest groups will pick up the torch...

Either way, it is up to the maintainer whether to support python2 split
builds. You might decide it is simply not worth it.
