Latest preview on Ubuntu 16.04.4 crashes

[magic51]

Hi!

Setting up a new server on Linux. 2.4 version works fine but when trying the preview version i get a Unhandled Exception Caught.

Running Ubuntu 16.04.4 LTS with Mono JIT compiler version 4.2.1 (Debian 4.2.1.102+dfsg2-7ubuntu4).

Starting with the workingFolder option to not "disturb" the working 2.4.

mono /usr/bin/vrsbeta/VirtualRadar.exe -nogui -workingFolder:/home/adminuser/.local/share/VirtualRadarBeta

Any ideas what goes wrong? I totally understand its a preview version but perhaps its something simple (im missing)?

Also thanks for the great work with this piece of software!

It's saying that 4.2.1 doesn't have an implementation for Array.Empty. Moving Mono up to a more recent version should do the trick.

Aha! Right now it should be Mono that i got via "apt-get" but that seems to be outdated. Current version should be 5.12.0.

Will take a look doing a manual install. Thanks!

Upgraded to 5.12 with instructions from mono web-site. https://www.mono-project.com/download/s ... wnload-lin

Working now. Thanks!
