How to fix Docker update “not available” in unRAID 6.8.3

Because something went wrong probably and it takes unRAID literally ages to issue an update. So here’s the fix!

(until you restart the server)

SSH into unRAID and edit this file: /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php

replace this line:

preg_match('@Docker-Content-Digest:\s*(.*)@', $reply, $matches);

with this

preg_match('@Docker-Content-Digest:\s*(.*)@i', $reply, $matches);
