Hi Raphaël, I'm not a maintainer of the pylint package, but I just let you know about your bug report.
This problem, as you reported, seems to resolve since pylint 2.5.0 in the upstream. FYI: https://github.com/PyCQA/pylint/issues/3256 Moreover, Debian stable (bullseye) already has a newer version of pylint, more than 2.5.0 at this moment. Then I believe the maintainer has resolved this problem. To confirm your problem today, I got the correct results shown below. (Sorry for accuracy, I use Debian sid.) --------------here----------------- $ lsb_release -a No LSB modules are available.
