@kevdog I've fixed the scripts on Github. You can issue the following commands
from your XO console to remove the incorrect symlink --
cd /usr/local/lib/node_modules/ sudo unlink xo-server-auth-github
The symlink will be properly recreated the next time you update the VM.
P.S. I believe your issue with the hanging backups is unrelated, so you may want to dig further in the logs to see if you can identify the cause.
