The package should be updated to follow the last version of
Debian Policy (Standards-Version
4.7.0 instead of
4.6.2).
problems
The package has a debian/watch file, but the last attempt
to use it for checking for newer upstream versions failed with
an error:
In debian/watch no matching files for watch line https://download.kde.org/stable/release-service/([\d.]+)/src/kalendar-([\d.]+)\.tar\.xz
testing migration
This package will soon be part of the auto-kmime transition. You might want to ensure that your package is ready for it.
You can probably find supplementary information in the
debian-release
archives or in the corresponding
release.debian.org
bug.
