A month before the release of 18.04, a change was released to make systemd journals persistent, but the setting SystemMaxUse was left unset in /etc/systemd/journald.conf
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1618188 The bug's regression analysis seems wrong, as it states: "The journald daemon has limits set for logs, meaning they will be rotated and discarded and should not cause out of disk-space errors." It also seems likely that no testers of 18.04 would discover this issue, since it requires running out of disk space after having accumulated large systemd journals over time. The documentation is here: https://www.freedesktop.org/software/systemd/man/journald.conf.html#SystemMaxUse= SystemKeepFree could be set, since it overrides the other values listed when the disk is running out of space. But I'm unsure, because if running out of disk space means that all the logs are silently truncated, then that is also a dangerous consequence on for instance a server where you could need logs to troubleshoot why disk space is running out... -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1790205 Title: systemd journals take up too much space, aren't vacuumed automatically Status in systemd package in Ubuntu: Confirmed Bug description: After running Bionic for 3 months, I had 2.6 GB of journals. I would not expect from a normal desktop user that they should have to run commands like `sudo journalctl --vacuum-time=10d`. I would nominate this command as a sane default to have running at each reboot to ensure that logs do not exceed 500 MB: sudo journalctl --vacuum-size=500M Supposedly, a server should by default retain more logs, so perhaps this should be implemented through a configuration package "systemd- configuration-desktop" as a dependency of the ubuntu-desktop meta package?
