Run 'systemctl daemon-reload' to reload units. Status in snapd: New Status in systemd package in Ubuntu: Fix Released Status in ubuntu-advantage-tools package in Ubuntu: Invalid Status in systemd source package in Noble: Triaged Status in ubuntu-advantage-tools source package in Noble: Invalid Bug description: [Impact] systemd may incorrectly mark units as needing a daemon reload, therefore unnecessarily printing the warning that a daemon-reload is needed for the changes to take effect. This is misleading to users, and particularly visible in cases like running apt update, since there is an apt hook (/etc/apt/apt.conf.d/20apt-esm-hook.conf) that starts two systemd services. [Test Plan] This bug can be triggered by running systemctl enable/disable on a non-existent unit. After that, calling systemctl start/status/etc. will show a false warning that the unit changed on disk. Hence, to test, simply: $ systemctl enable somethingthatdefinitelydoesnotexist.service $ systemctl status systemd-resolved.service $ apt update On an effected system, warnings will be shown when calling both commands after the "enable non-existent unit" step. [Where problems could occur] This patch fixes a previous commit by ensuring that the manager->unit_file_state_outdated flag is set *only* when some modifications succeeded, but the overall operation failed. In cases where everything fails, it is not necessary to set the flag. Since the patch is restricted to this area, any regressions from this patch would most likely also be related to the NeedDaemonReload property of units. [Other information] The patch is from upstream: https://github.com/systemd/systemd/pull/32610/commits/d69cba3bfffc7b1e3197e2a34b459db13b1e1cb7#diff-84bbf3361da4139a5620a035ebd24f50a0e4d4ece7952dc2d8b4325e6ebdf6e0L2320 [Original Description] I recently started seeing the following warning messages when I run `apt update`. $ sudo apt update Warning: The unit file, source configuration file or drop-ins of apt-news.service changed on disk. Run 'systemctl daemon-reload' to reload units. Warning: The unit file, source configuration file or drop-ins of esm-cache.service changed on disk. Run 'systemctl daemon-reload' to reload units. ... apt-news.service for example is in /lib/systemd/system/apt- news.service and it's a static file managed by the package.
