This is a known error - for now you have to symlink the libunwind library on your system to point to libunwind.so.1, e.g. sudo ln -s /usr/lib/libunwind.so.8 /usr/lib/libunwind.so.1

why does such a problem exist at all, and what is the difficulty of solving it? (interested as a developer)

As you have noticed, Arch Linux ships its libunwind library under a different name and the executable cannot find it. The executable is built on an Ubuntu server and thus launches flawlessly on Ubuntu distros. We're working on a workflow that'll produce AppImage executables able to run on all distros out-of-the-box - see: https://github.com/TeamHypersomnia/Hypersomnia/pull/270

As for the dependency, it looks like LLVM's libc++ is using it to unwind the stack when handling exceptions. I've been trying to remove that dependency (even today actually) but have been unsuccessful so far. Surprisingly, building the same application on Arch Linux does not produce that libunwind.so.1 dependency, whereas building on Ubuntu does.

Hey there! We're now shipping the game in the portable AppImage format. This should solve all problems you have experienced with the missing libraries:
