I know this is an old thread, but I'm getting the same Install error plugin: unRAIDServer.plg Plugin failed to install I'm on v7.2.2 and tried to upgrading to 7.2.3 and even the new 7.3.0 with the same error. I've proactively attached my diagnostics zip file for your reading pleasure. Thanks in advance for any help you can give.
