Package: lintian-brush Version: 0.70 Severity: important As seen in https://salsa.debian.org/cinnamon-team/cinnamon/-/merge_requests/9, upgrades from debhelper 11 to debhelper 12 by lintian-brush will sometimes result in files no longer being installed.
The relevant bit from the debhelper changelog appears to be: The build systems meson and autoconf no longer explicitly set the --libexecdir variable and thus relies on the build system default - which should be /usr/libexec (per FHS 3.0, adopted in Debian Policy 4.1.5). If a particular upstream package does not use the correct default, the parameter can often be passed manually via dh_auto_configure(1). E.g. via the following example: override_dh_auto_configure: dh_auto_configure -- --libexecdir=/usr/libexec Note the -- before the --libexecdir parameter. Looking at the logs, it seems like the old build passed in --libexecdir=\${prefix}/lib/x86_64-linux-gnu lintian-brush can automatically set this flag for packages that it upgrades to debhelper 12, but ideally it would only do so for those packages that ship anything in libexec. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 5.3.0-2-amd64 (SMP w/2 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages lintian-brush depends on: ii devscripts 2.20.3 ii python3 3.8.2-3 ii python3-breezy 3.1.0-3 ii python3-debian 0.1.37 ii python3-distro-info 0.23 ii python3-dulwich 0.20.2-1 ii python3-iniparse 0.4-3 iu python3-ruamel.yaml 0.16.10-2 Versions of packages lintian-brush recommends: ii dos2unix 7.4.0-2 ii gpg 2.2.20-1 ii libdebhelper-perl 13.1 ii lintian 2.80.0 ii python3-asyncpg 0.20.1-1+b1 ii python3-levenshtein 0.12.0-5+b1 ii python3-pyinotify 0.9.6-1.3 ii python3-toml 0.10.1-1 Versions of packages lintian-brush suggests: pn gnome-pkg-tools <none> ii postgresql-common 215 -- no debconf information
