TL;DR: don’t use generalized unpacking here: !2, 3.5 /home/glci/builds-stage1/ytsywSZu/0/petsc/petsc/config/BuildSystem/config/packages/tchem.py generalized unpacking requires 3.5+ ——— vermin is a python package that checks which python version is required to run a particular python script. Petsc targets python 2.6 or lower and 3.4 or lower, however your change would make python 3.5 the new minimum: Minimum required versions: 3.5 Incompatible versions: 2 Target versions not met: 2.6-, 3.4- ctrl-F for “3.5” will find the file and reason in the output.

I do not understand what is being tested or where the failure lies?
