For some reason jpylyzer does not build anymore on Debian:

Very odd. I can't reproduce the error as I don't have Python 3.9 installed, but as the offending six module is only used/needed under Python 2.x, I made the import conditional on the Python version, see:

https://github.com/openpreserve/jpylyzer/commit/4e3cd5cc20a462f3cb9da832ae6c2b19c8218379

I just created a 2.0.1 bugfix release for this:

https://github.com/openpreserve/jpylyzer/releases/tag/2.0.1

Let me know if this fixes the issue! If so, I'll also merge these changes into the development branch of the upcoming 2.1 release.

That worked !

Perfect, thanks for confirming this!
