I installed League of Legends on Ubuntu 14.04 LTS. It installed, but when I click the launcher, I get an immediate bug splat. I'm following instructions how to fix this problem but this one came up and I have no idea how to install it (I'm brand new to Linux):
Download it from here: https://bitbucket.org/Xargoth/tuxlol/wiki/Home Unzip anywhere you want
Enter the folder you just unzipped (where there is the tuxlol.exe file) and execute it:
$ mono tuxlol.exe patch --dir "LEAGUE_OF_LEGENDS_DIR"
Obviously, replace LEAGUE_OF_LEGENDS_DIR with your League of Legends directory. In my case, it's installed here:
~/.PlayOnLinux/wineprefix/LeagueOfLegends/drive_c/Riot Games/League of Legends/
PS: You'll have to reaply this patch everytime a new LoL update is released.
