Did this behavior use to work in the previous version?

Irrelevant

Steps to Reproduce (for bugs)

I ran "Install.sh".
Then "ServerStart.sh".
Both files have permissions.

Forge for Minecraft 1.12.2 requires you use Java 8.

You can install this on Ubuntu by issuing the command

sudo apt install openjdk-8-jre

You then set it as the default by executing:

sudo update-alternatives --config java

And entering the number corresponding to Java 8 followed by the return key.

Note: typed this on my phone, watch out for errors as a result of autocorrect.

Thanks for the quick reply.

This kind of crucial information should appear in the "readme" or anywhere on your github page (or even on your curse thing page).
