Hello Dimitri, After a quick check it looks like this service is still in inactive (dead) state even after a reboot.
ubuntu@kernel04:/lib/systemd$ sudo systemctl status systemd-timesyncd ● systemd-timesyncd.service Loaded: masked (Reason: Unit systemd-timesyncd.service is masked.) Active: inactive (dead) ubuntu@kernel04:/lib/systemd$ file /lib/systemd/system/systemd-timesyncd.service /lib/systemd/system/systemd-timesyncd.service: cannot open `/lib/systemd/system/systemd-timesyncd.service' (No such file or directory) And there is no "systemd-timesyncd.service" file at where is should be. So yeah it's not running, our testing tool did not check the state first before trying to stop / start it. $ sudo systemctl edit systemd-timesyncd Cannot edit systemd-timesyncd.service: unit is masked. Let me see if I can un-mask it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1882505 Title: ubuntu_ltp_syscalls failed to run on Focal s390x, unable to restart systemd-timesyncd.service To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1882505/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
