I have a fresh install of ubuntu 20.04 and I have followed all of the steps listed on the linux install page. when I run "mono UORLauncherLite.exe" from the terminal, I get the following error. "The entry point method could not be loaded due to Could not load file or assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies" I've tried to research and troubleshoot, but I'm not finding any solutions. Does anyone have any suggestions?
If anyone stumbles across this, I installed mono-devel and mono-dbg and this seemed to fix the issue. I still get the error " Failed to load module "canberra-gtk-module" Can't find custom attr constructor image: /home/user/uorlauncher/UORLauncher.exe mtoken: 0x0a00000c due to: Could not load file or assembly 'PresentationFramework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies." However, the launcher now starts.
Spoke too soon. The launcher will run, however, when I attempt to run the game by clicking Play "UO:Renaissance", I get the following error System.IO.FileNotFoundException: Could not load file or assembly 'PresentationFramework, Version=4.0.0.0
