Regarding updating, I actually did that just before my initial post for unrelated reasons but I just tried again-there were a handful of updates but still nothing.
OK thanks for following up.
I checked the binary of the free-but-older-version of the game v.3.63 tonight, and after investigating it, I realized in this particular case, ldd output, at least the default output as we suggested/repeated earlier wouldn't have mattered. Still good advice for most other cases. Your post too demonstrates the fact that, ldd is not spitting out what UrW needs.
While it is possible to make ldd tell us more with extra parameters, probably not needed at this stage.
Instead, please try these below, and when prompted, just press Y and accept the disk cost & let apt auto-install any dependencies, as usual.
EDIT: Actually, I need to clarify that this is written for and tested on Ubuntu latest LTS Desktop 22.04 and UrW 3.63 (free-but-outdated) version and tested only on this version.
If you are however on the latest and greatest version of this game (v.3.72) let us know.1. Install the SDL2 library components:
apt install libsdl2-2.0-0 libsdl2-image-2.0-0 libsdl2-mixer-2.0-0 libsdl2-net-2.0-0
2. Also install this audio dev lib:
apt install libjack-dev
Then open the console and type "urw" and let us know the outcome. If this does not work we will need more info from system.
Edit: clarified on what OS/Game versions this suggestion was tested on.
