[HOW] Best practice to avoid DRC/ERC errors due to different KiCAD versions

[bene42]

What do you want to achieve?
I try to build a project by github actions

Do you have some PCB/Schematic to use as example?
https://github.com/eurovibes/com4bbb

Do you have some configuration file (.kibot.yaml) that you are using?
see file com4bbb.kibot.yaml

Environment (please complete the following information):
Where are you running KiBot:

• In a CI/CD workflow? Gitlab Actions
• In a GitHub action? Which tag are you using? v2_k9 / v2_dk9
• Using a docker image? No direct use -> github action
• Using a desktop system? Which OS, distro and version? KiCAD on Linux: Debian sid :

Additional context
While running DRC/ERC works fine without errors on the development system it fails in CI:

GS.exit_with_error(msg, DRC_ERROR)

This happen occasionally due to updates in KiCAD footprins and symbols in the point releases.

What is the best practice to avoid these errors?
