Dear Maintainer, In python-requests-cache upstream ships one python module, probably by mistake, as executable. Lintian reports this as a warning: W: python3-requests-cache: executable-not-elf-or-script [usr/lib/python3/dist-packages/requests_cache/models/response.py] I'm fixing this now with the debian/rules lines: execute_after_dh_fixperms: chmod 644 debian/python3-requests-cache/usr/lib/python3/dist-packages/requests_cache/models/response.py This commit contains my fix: https://salsa.debian.org/plenae/python-requests-cache/-/commit/a859e613293c9bd6621d344b6596c6a6635e1fa1 The previous commit illustrates the issue. It would be better to have dh_fixperms understand which files in python packages are modules and should not be executable, and which are scripts, which should be +x. Best regards, Pieter
