Fix Recommendation

The systemd-journald logs are by design stored with root:systemd-journald owner and group respectively.

If any files are found with different ownership, run the following command to correct them:

$ sudo chown -R root:systemd-journald /var/log/journald

Check Contents

Verify the journald directories and logs are group-owned by "systemd-journald" by executing the following command:

$ sudo find /var/log/journal -not -group systemd-journal

If any directories or files are returned, this is a finding.
