The as-installed testing for this package
did not pass
(log).
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://github.com/libcgroup/libcgroup/releases .*/libcgroup-(\d\S+)\.tar\.gz
testing migration
This package will soon be part of the auto-libcgroup 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.
