Source: lintian Version: 2.5.118 debhelper 12 was released this week. With this release, compat level 12 is now the recommended compat level. [1] Therefore, I suggest bumping data/debhelper/compat-level recommended=12 experimental=13 [1] https://manpages.debian.org/unstable/debhelper#Supported_compatibility_levels Thanks, Jeremy Bicha
