Bug#1125004: Type=oneshot lost for anacron.service ?

And since some daily anacron jobs might have a random delay of a couple of minutes the anacron.service appears to be hung. So I tried to say already I could not reproduce this issue when I tested with a new install of bookworm upgraded to trixie. anacron.service (triggered by the timer) was running during the upgrade with some jobs completed and some waiting to run. anacron received SIGUSR1 and exited during the upgrade and then the jobs that did not run were started again with a delay. Since your command output shows systemd-tty-ask-password-agent watching, I think the hang is from daemon-reload initiated from anacron's postinst on upgrade in your environment. This bug report will close when there is another release of anacron, so please submit a new bug report with more information to reproduce and help debug if it continues to be an issue.

So I could not reproduce a hanging upgrade from Debian 12 (bookworm) to Debian 13 (trixie). anacron's jobs from the previous anacron.service are killed before the "apt dist-upgrade" anacron.service is started and the upgrade finished with anacron.service running. I think systemd-tty-ask-password-agent waiting for a password is the hang which may occur from the daemon-reload [1] in your environment? Is there something different from a default install or permission changes?

Ain't the WantedBy trigger running the anacron.service at boot time, ignoring the anacron.timer? This is surely unexpected. Do you think this should be added to the documentation? Regards Harri

Thank you I don't see Type set in the service file before. Setting Type to oneshot instead of the default simple type should be okay. I didn't see any issues when I tested setting the type. I also checked the other service files that have timers on my system, and each of those have this type set so I will add this for the next release. When it is released into unstable, this bug will close. -- Lance Lin GPG Fingerprint: 4A31 DB5A 1EE4 096C 8739 9880 9036 4929 4C33 F9B7 OpenPGP_0x903649294C33F9B7.asc Description: OpenPGP public key OpenPGP_signature.asc Description: OpenPGP digital signature
