1. in the betacraft download page, you (obviously) need to download the linux version
2. it will download a .jar file. right click any empty space in the folder that contains the .jar file. you will see a button similar to "Open in Terminal". click it.
3. in the terminal, type: [b]java -jar launcher-1.09_17.jar[/b], then press enter.
enjoy! :mrgreen:
NOTE: if your desktop environment is KDE and you dont have a different terminal, you might have a terminal called "Konsole".

2. Make sure Qt5 is installed. For example, on Ubuntu/Debian: sudo apt install libqt5core5a libqt5network5 libqt5gui5
3. Take care of the installation. For .deb: sudo dpkg -i multimc_1.6-1.deb For PKGBUILD (Arch): Follow the instructions in the GitHub repo to build and install.
For tar.gz: Execute these following commands (make sure to follow the order, please. I'm serious.) tar -xvzf multimc-*-linux.tar.gz cd MultiMC chmod +x MultiMC ./MultiMC
Then, you're pretty much done. Enjoy.
Feel free to PM me for any inquiries or any questions, I'll try to reply in due time.

You could also get Prism Launcher over MultiMC, basically the same thing but with active development. That's what I use with the Betacraft's LegacyFix applied.

I would honestly be wary of MultiMC forks like Prism Launcher, I tend to trust the original publisher. But if it works for you, that's alright. :-P
