Hello yesterday i purged packagekit. Today i still get a notification about newly avail updates. So packagekit is not the cause.
i get this in syslog: Apr 19 20:07:03 localhost systemd[1]: Started Daily apt activities. Apr 19 20:07:03 localhost systemd[1]: apt-daily.timer: Adding 7h 21min 11.609254s random time. Apr 19 20:07:03 localhost systemd[1]: Startup finished in 11.500s (kernel) + 1min 16.023s (userspace) = 1min 27.524s. Apr 19 20:07:03 localhost systemd[1]: apt-daily.timer: Adding 7h 19min 33.003847s random time. After looking at it i think the cause is this local setting: APT::Periodic::RandomSleep "10"; This setting is from the old cron job where apt would run only after the default 5min delay from anacron. i changed that now to 180s. Obviously this "bug" is wrongly added to packagekit. If maintainers could live with that one more day i clean that up in b.d.o tomorrow. kind regards, Thilo
