Not sure where to bring this up. I'm new to Gitlab and reaching out there seems difficult. In any case, the command for the Wine installation on Ubuntu is wrong in the Wiki: https://gitlab.winehq.org/wine/wine/-/w ... ian-Ubuntu
The command in the wiki is correct; it installs the package with compatibility symlinks that allow the user to use our Wine packages as the system default, and also pulls in the actual Wine packages. The command you suggest is only for people who don't want our package to be the system default. This is primarily people who want to install more than one package (-stable,-devel, -staging), and if you scroll down the page to the Notes section, you will see that is described in detail.
If you're on Ubuntu 24.04, there is no stable package yet because 24.04 was not yet released when 9.0 came out. There will be stable packages for 24.04 whenever the next stable release comes out. In the mean time, you can use either our devel or staging packages, or use Ubuntu's distro Wine package, which is 9.0.
