I had a few hang ups with installing Minecraft Forge Server on Debian 8 a few months back and wrote down the process. I just got around today to cleaning up old Drive docs and found it. Hopefully this can help someone having issues. I am still exploring Linux, so if anyone has any corrections or simplifications I am always eager to learn. I desire to contribute to the collaborative knowledge for anything Linux.

Root

Install latest Java version:
echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" | tee /etc/apt/sources.list.d/webupd8team-java.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt-get update
apt-get install oracle-java8-installer

Download Forge Installer .jar manually. (ad.fly ad-wall prevents CLI download)

Navigate or path to the file, then run via Java:
java -jar forge-1.7.10-10.13.2.1291-installer

Dont forget to change the EULA.TXT to true! (If I remember correctly I had to attempt to run the server once to generate the eula.txt)
nano eula.txt

Hope this helps someone! The TacoTEK minecraft server was eventually moved to the TACOstar rack-mounted server, hosted by [TACO]Kraknar for the glory of TACO-kind
