Source: lintian Version: 2.5.118 The description of tags like package-uses-experimental-debhelper-compat-version and package-uses-deprecated-debhelper-compat-version suggest 2 different ways of setting the debhelper compat level.
It should instead suggest the new debhelper-compat Build-Depends method which looks like it is now the recommended way to set the compat level, regardless of whether you use compat level 12 yet. See https://manpages.debian.org/unstable/debhelper#COMPATIBILITY_LEVELS Thanks, Jeremy Bicha
