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 owned by "root" by executing the following command:

$ sudo find /var/log/journal -printf "%p %u\n"

/var/log/journal root
/var/log/journal/8960867736094c2089638a86c43fd755 root

If any occurrences of owner are not "root", this is a finding.
