Error - Install umu to use Proton

Support

Lutris v 5.17

I needed a break from playing Guild Wars 2, logged out of Guild Wars 2 and closed Lutris but when I came back, after loading Lutris, and tried to run Guild Wars 2 again, a pop-up window said umu needed to be installed to use Proton. This error pop-up occurred for the other games I use Lutris to run.

Here’s the message detail:

Hi same issue here.

Reddit has some posts regarding that :

One post says to install UMU using release page on their github. I’ll give it a try

Have the same issue. Installed umu-launcher from AUR. It gave a pressure-vessel not found error when trying to launch the game. Putting the latest release into ~/.local/share/umu helped. Now everything works.

Thank you man! Definitely worked for me, Proton(Latest) is available again as a runner and works.
