As stated in the title, everything went smoothly until the pre-reqs. But even after the pre-reqs didn't install properly, I was still able to get the launcher to verify and try to update, as per the steps in a previous thread. But I got stuck in the the, "Close launcher... Needs to update loop" and I don't think it's going to work properly due to those pre-reqs not installing.
Currently running Ubuntu 16.04.
Thanks for your time.
