Hi, This is because upstream deleted the "YES" alias from astroid on https://github.com/PyCQA/astroid/commit/36fa294e9b84885d95a03b1fbc07da63e6d6a79b
This issue was opened on pylint-django ( https://github.com/PyCQA/pylint-django/issues/201) They resolve the issue adding on setup.py the requirement of astroid == 2.0.4. I've push to salsa a patch adding the 'YES' alias on pylint-django ( https://salsa.debian.org/python-team/modules/pylint-django/commit/c3f38068cda75d4125b4e6274598a8f4acd892bd#58ef006ab62b83b4bec5d81fe5b32c3b4c2d1cc2 ) Cheers -- Arias Emmanuel http://eamanu.com Github/Gitlab; @eamanu Debian: @eamanu-guest
