Bug#1037187: bullseye-pu: package libprelude/5.2.0-3+deb11u1
Package: release.debian.org
Severity: normal
Tags: bullseye
User: release.debian.org@packages.debian.org
Usertags: pu
Control: block 996878 with -1
Control: affects -1 + src:libprelude
Control: tag 996878 patch pending
[ Reason ]
'import prelude' fails in python3 due to some missing symbol, rendering
python3-prelude useless.
[ Impact ]
'import prelude' will not work, breaking some packages depending on that
[ Tests ]
manual 'import prelude' with the fixed package in bullseye worked
added superficial autopkgtest testing the import
[ Risks ]
Low. The patch cannot make the unusable pyton module worse.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
only backported python module fixes from sid
[ Other info ]
