Dofus
Installation
Install the ankama-launcherAUR package.
Currently the game files are installed under the "games" group with group writability. You can add your user to the group (usermod -a -G games username) to take advantage of this. Otherwise, you may need to enter your password in order to update the game files.
Troubleshooting
When debugging problems, it is helpful to set the environment variable AK_LOG_CONSOLE=1 when running Dofus. It will then print detailed logs in the console.
A known problem is that some systems require unset SESSION_MANAGER in the environment, to avoid crashes on start up.
Occasionally the updater cannot function because of a leftover process from previous runs. Killing transition processes can solve this problem.
