Overnight I noted that my cloudron install failed to update. Status in Web UI was "update exited with code 1 signal null"

The logs says :

Aug 19 09:34:23 box:shell update (stdout): cloudron-updater is still active. will check in 5 seconds

I can't make heads nor tails of what to do with that log. Is there a step I am missing
