Hi, I didn't personally figure out that Lutris had this option until doing this myself, so I figured I would try to share.

I've had guides try to get me to patch in wine installs manually through terminal commands and shifting folders around, but Lutris actually has a built-in feature to fetch and install runners a bit hidden in the GUI.

If you refer to the image I uploaded, you can see the basic Lutris in the background, I've circled the area you need to go to on the left. The "Wine" category, when you hover it, will have a little box and a gear. If you click on the box, it will bring up the menu in the foreground. It will have listings of all sorts of runners you can install for usage in Lutris. No fiddling required. Install wine-ge-lol-8-27 from here for the as of current most recent League fix.

When you have this installed, you can close this menu, and change your league runner to it. All done. If you don't know how to do this, these are the steps:

• click League of Legends in Lutris
• on the bottom left, next to the play button, click the up arrow just to the right of it
• click "Configure"
• in the top menus, click "Runner options"
• the first option should be "Wine version", click this and find your newly installed wine-ge-lol-8-27-x86_64
• click the green "Save" in the top right

And you should be good to go! This updates your league runner to the current stable version without having to reinstall or mess with the terminal. I hope this was helpful to anybody out there and not just obvious to everyone hahah.
