The installation of Blizzard Battle.Net following the script provided by Lutris gets stuck after login on the Battle.Net Agent. The agent opens but the installation window prints many error messages that made me believe the installation had really failed. However the solution was very simple and quick: I just had to close the Agent’s window and wait for one more minute, then the installation finished successfully and I could open the agent and install my games.
I wonder if someone could add a warning on the script telling the user to close the Agent’s window after login. That could reduce a lot of frustration.
