Have followed the install instructions but
Launchpad is having difficulty building the packages. We’ll inform you once it’s built.
Should be good now.
For waiting, on Ubuntu, you can easily download Lutris from git:
open a terminal and type this command:
$ git clone https://github.com/lutris/lutris.git
go to the binary folder:
$ cd lutris/bin/
type this command to launch it:
$ ./lutris
