[Debian-pan-maintainers] Bug#1029775: pyhst2: FTBFS with setuptools 66: Invalid version: '2020ca'

[Didier 'OdyX' Raboud]

So. I have a much shorter (and better) patch, that I'll upload to DELAYED/5 in 
few minutes.

See the attached patch, which consists of setting the setup.py version to a 
PEP-440-compliant Debian-specific version (which I have confirmed to sort 
bigger than "2020ca"). This fixes the FTBFS.

I've also pushed this as an MR on your VCS repository there:

Best,

OdyX
