Bug 2.47.3 Linux(Ubuntu) Update Issue

Hey there. I'm new to RuneBot on Linux (I use the "Standalone" version), and i'm running the issue that follows:

> Start up Runemate.Jar (Standalone Version)
> Says it needs to close for an update
> Close for update
> Start Runemate.Jar again
> Same message come up "close for update or manually update"
> I chose manual this time
> Downloaded new Runemate.Jar file (Standalone Version)
> Started up new Runemate.jar file
> Running into the same problem.

So I have tried also updating any RS3 files through the RS official launcher, which in result came to the same conclusion.

Running Java version 8u131 x64(Oracle Corporation)

Please help!
