Can't tell if this is a regression, as I haven't find a way to reproduce it. But I do see similar reports on the Internet [1] After checking the systemd service timers, it looks like this is caused by the logrotate.service: $ sudo systemctl list-timers --all NEXT LEFT LAST PASSED UNIT ACTIVATES Fri 2019-01-25 06:18:58 UTC 1h 40min left Thu 2019-01-24 06:34:15 UTC 22h ago apt-daily-upgrade.timer apt-daily-upgrade.service Fri 2019-01-25 09:15:54 UTC 4h 37min left Fri 2019-01-25 03:43:24 UTC 55min ago apt-daily.timer apt-daily.service Fri 2019-01-25 17:02:47 UTC 12h left Fri 2019-01-25 04:20:17 UTC 18min ago motd-news.timer motd-news.service Sat 2019-01-26 00:00:00 UTC 19h left Fri 2019-01-25 00:00:37 UTC 4h 38min ago logrotate.timer logrotate.service Sat 2019-01-26 04:02:38 UTC 23h left Fri 2019-01-25 04:02:38 UTC 36min ago systemd-tmpfiles-clean.timer systemd-tmpfiles-clean.serv Mon 2019-01-28 00:00:00 UTC 2 days left Wed 2019-01-23 10:44:18 UTC 1 day 17h ago fstrim.timer fstrim.service n/a n/a n/a n/a snapd.snap-repair.timer snapd.snap-repair.service 7 timers listed.
