I know a lot of people have been facing issues setting up osu! on Linux. Most of the guides online are either outdated or just all over the place, so I hope to maintain a good guide here that is relatively easy to follow.
I'd like to start by saying I have only tested this on Debian-based distributions, however it should work fine on others.
If you have any problems during or after installation, please don't hesitate to contact me on Discord (tsunyoku#0066) and I will try my best to help.
