Nice guide, ty so much. It works perfect on the Ubuntu 22.04.2 LTS. The only thing I didn't understand is how to add mp3 to create beatmaps? Drag&drop files directly causes the game to crash, and winefile does not support drag&drop. I tried copying existing folders and modifying the beatmap file, but I didn't find a complete description of each map property in the file. How to guess the beatmap number is also unclear. Is it possible to upload maps with such modifications? At the moment, this is the most realistic option for creating maps on linux that I see.
