In 22.04 it's still handled by run-parts, and the man page documents it as such. Specifically by $ strings /lib/x86_64-linux-gnu/security/pam_motd.so | grep run-parts /usr/bin/env -i PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin run-parts --lsbsysinit /etc/update-motd.d > /run/motd.dynamic.new in its primary use case. The "fetch new ads on boot" motd-news.service for this bug report runs one of the scripts directly, but the directory is still a run-parts input. We could disable scripts by renaming them to something that won't be found by the '--lsbsysinit' file patterns, but that would only solve the problem for "at login" updates, not the "at boot" updates through systemd. > It's merely to avoid harmless surprise and keep the old sysadmins happy, Service errors is hardly a "surprise", and you don't need to be condescending about it. wontfix (wontfix) wrote: > and that is to set ENABLED=0 in /etc/default/motd-news." > > This file no longer exists by default in Ubuntu 22.04 Jammy. $ grep VERSION /etc/os-release VERSION_ID="22.04" VERSION="22.04 LTS (Jammy Jellyfish)" VERSION_CODENAME=jammy $ dpkg -S /etc/default/motd-news motd-news-config: /etc/default/motd-news $ apt show motd-news-config Package: motd-news-config Priority: optional Source: base-files Task: cloud-image, ubuntu-wsl, server, ubuntu-server-raspi APT-Manual-Installed: no [several header elided] It certainly existed by default from the beginning of the server installation I'm working with.

The order of script execu‐ tion is determined by the run-parts(8) --lsbsysinit option (basically alphabetical order, with a few caveats). So sysadmins are used to "chmod -x" motd fragments from /etc/update- motd.d/ to prevent their execution. When doing so for /etc/update- motd.d/50-motd-news, I noticed that motd-news.timer was still trying to execute the motd-news.service unit which then logged a failure: systemd[3704]: motd-news.service: Failed to execute command: Permission denied systemd[3704]: motd-news.service: Failed at step EXEC spawning /etc/update-motd.d/50-motd-news: Permission denied systemd[1]: motd-news.service: Main process exited, code=exited, status=203/EXEC systemd[1]: motd-news.service: Failed with result 'exit-code'. systemd[1]: Failed to start Message of the Day.
