Package: certbot Version: 0.31.0-1 Severity: minor While looking at your certbot package, I noticed that in unstable it uses
override_dh_installsystemd: dh_installsystemd --no-start --package=certbot dh_installsystemd --package=certbot certbot.timer The first call "dh_installsystemd --no-start --package=certbot" will act on all systemd unit files, including certbot.timer. Then you add a second call "dh_installsystemd --packaaptge=certbot certbot.timer" which will generate a lot of duplicated code. Just have a look at /var/lib/dpkg/info/certbot.postinst or debian/certbot/DEBIAN/postinst. I assume you want something like this instead: override_dh_installsystemd: dh_installsystemd --package=certbot --no-start certbot.service dh_installsystemd --package=certbot certbot.timer The first call will act on certbot.service, the second on certbot.timer This was broken in https://salsa.debian.org/letsencrypt-team/certbot/certbot/commit/0410bde34cefb73263a9754d57d224badbfcce1c afaics Regards, Michael -- System Information: Debian Release: buster/sid APT prefers unstable APT policy: (500, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-3-amd64 (SMP w/4 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages certbot depends on: ii python3 3.7.2-1 pn python3-certbot <none> certbot recommends no packages.
