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://gitlab.freedesktop.org/upower/upower/tags?sort=updated_desc archive/v(?:[-_]?[Vv]?(\d[\-+\.:\~\da-zA-Z]*))/upower-v\d\S*(?i)(?:\.(?:tar\.xz|tar\.bz2|tar\.gz|tar\.zstd?|zip|tgz|tbz|txz))
testing migration
This package will soon be part of the auto-libplist 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.
