Only because the maintainer did something wrong when he removed the Install section. At https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913584#5, Michael Biebl said: Starting via multi-user.target should either be re-introduced or the symlink removed on upgrades. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ So, removing the symlink would have been the other possibility. Running anacron on upgrades is not a big problem, but it makes the start time of the daily jobs less regular without any good reason when an upgrade is done between midnight and 07:30. For instance, if an upgrade is done on day 3 at 00:10, Day 1: 07:30 (with a delay of up to 5 minutes) Day 2: 07:30 (with a delay of up to 5 minutes) Day 3: 00:10 Day 4: 07:30 (with a delay of up to 5 minutes) So I would say that it would be better to avoid that. > If there is an actual issue with the install section, I will debug > this via a new issue since this one will close with the next release > of anacron 2.3-50. I confirm that upgrading to anacron 2.3-49 between midnight and 07:30 did not hang: Apr 14 02:24:16 qaa systemd[1]: Started anacron.service - Run anacron jobs.
