Linux: Listener immediately stops after starting.

[RobotRoss]

sACNView stops listening immediately after a request to start with no data being returned on Linux. sACNView on the same machine running Windows, with the same network configuration, works properly.

[docsteer]

This is a bit strange - I had a look and I don't see an obvious reason this would be happening. Could I get you to:

• Try this with the latest Linux beta (https://github.com/docsteer/sacnview/releases/download/v3.0.0-beta.2/sACNView-x86_64.AppImage)
• If it's still a problem:
  • Let me know the Linux distribution and version you're using
  • Let me know what you see in the "Unicast" and "Multicast" columns in the program info screen.

[RobotRoss]

I can confirm that the problem is still present with the beta version.

I've tried to reproduce this and haven't had any success so far. I installed SilverBlue in a VM and was able to install sACNView and receive sACN OK. Silverblue is a little bit unusual in how it deals with app installation for a Linux system, so maybe related to that, but haven't been able to reproduce anything. It also works fine on several other linux systems. So I would ask - would you maybe be able to boot Silverblue from a live USB stick or something, and see if the problem still occurs? Wondering if it's something specific to your machine or installation.
