Ok, so here is the bug and problem i have noticed i am not the only one finding it absulutly impossible to install league of legends in any way. i tried EVERYTHING. i am using ubuntu 16.04 and not wine nor playonlinux has been able to install league. i just would request that this is fixed and updated as soon as possible. i really tried everything and researched the problem out as best i could. now its up to you i have also contacted player support on their side. so if you can fix it i would apreciate it.. league is my favorite game.
And i apologize for the dramatic title, but i hope you can sympathizeee.
