I am a new user to Ubuntu 16.04 and used winetricks to install the Kindle app and it starts up just fine, Amazon makes it a little hard to register by generating a random one time new password, which I did and it seemed to be successful and Amazon verifies the existence of this new Kindle for PC app but when I try to sync the library it gives me an unable to connect message. If I close the app and restart, it goes to the registration process again, creates yet another Kindle for PC version and repeats the entire frustrating process.
I'm hoping someone has already solved these problems and can tell me what I need to do to make it work.
