Bug#1040179: spyder: Spyder reports missing dependency: pylsp_black >=1.2.0 : None (NOK), but python3-pylsp-black 1.2.1-2 is installed

[Julian Gilbey]

Hi Mike,

Thanks!  Oh dear, so that's not the cause of the problem, as I
feared.

Could you try running the attached script?  It will check if there are
any installed Debian packages which have an invalid version number;
that was the cause of this problem in #1032995.

Best wishes,

   Julian
