Help with Arma 3 wasteland?[Solved]

I've been using Windows for Arma 3 for a while, and that was the sole reason for me to use Arma 3. Today I found out it worked on Linux, so I downloaded it on my Ubuntu Gnome HDD. The mouse was not working, found that fix quite fast. But for some odd reason it is at version 1.42. The Wasteland server I always play requires me to have 1.5, is there a way for me to get 1.5 on my computer, or should I beg them to make it so people with 1.42 can join?

You have to use 1.42 until they decide to release 1.50 and battleeye for Linux.

Just run a 1.42 wasteland server or join one.
