It seems like the "markdown" package is now orphaned in Debian:

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=466330

That package seems to have been in life support for a decade or more,
based on the Debian changelog and the above discussion.

How about using python-markdown instead?  It seems to be actively
maintained and no-frills enough.  See:

    https://python-markdown.github.io/#goals

It has optional extensions, such as one for tables.
