[Debian-astro-maintainers] Bug#891198: python3-astropy: generic_parsetab.py should be rebuild with system ply

[Yannick Roehlly]

Package: python3-astropy
Version: 3.0-2
Severity: normal

Hi,

Importing astropy.units raises a warning:

In [1]: from astropy import units as u
WARNING: yacc table file version is out of date
WARNING: Couldn't create 'astropy.units.format.generic_parsetab'. [Errno 13] 
Permission denied: '/usr/lib/python3/dist-packages/astropy/units/format/generic_parsetab.py'
WARNING: Couldn't write lextab module 'astropy.units.format.generic_lextab'. 
[Errno 13] Permission denied: '/usr/lib/python3/dist-packages/astropy/units/format/generic_lextab.py'

I think this is because this file was compiled with version 3.8 of ply while
Debian uses the system python3-ply package which is version 3.11.

Regards,

Yannick
