It seems, that CCP have changed the login process on server side so does it no more compatible with the linux version of the launcher. If CCP not update the linux launcher or change the login behaviour there is no way back, only the possibilities to use the windows launcher with wine or Steam Play Beta. Have it tested with Debian Stretch, Wine 3.15 and nvidia driver version 390.77 from Debian Backports.
@CCP_Falcon It would be nice from CCP that she give a clear statement about the linux launcher and when she are not willing to support them, then a statement, that the linux launcher are no longer usable.
I will on the end of this month shut down my site about the linux launcher (see EVE Installing) and the downloads for him, because there is no more to change for me to make evesetup better or compatible to the server side changes.
