Systemd Journal

The issue

The Supervisor needs access to the systemd journal to access logs of individual system components and add-ons. These logs are limited or not available at all if the journal is not accessible.

The solution

The systemd-journal-gatewayd service needs to be running on the host and exposed to supervisor via unix socket.

If using Home Assistant OS, update to version 7 or later.

If using Home Assistant Supervised, run the following on the host:

sudo apt install systemd-journal-remote -y

and then reboot your system

If after upgrading you are still facing this error, reinstall systemd-journal-remote with the following command

sudo apt-get install --reinstall systemd-journal-remote

and reboot your system

If you still see this issue then run the supervised installer on the host as the supervisor service may need an update as well.
