At first I thought of filing a bug report, then after few more issues I thought of recording a video and make a tutorial out of it for new-to-Linux users, but ultimately it was so unstable and buggy that I got to the conclusion that it (i.e improvement in Fedora Gnome installation) is not even worthy of my time anymore.
I have been a fan of Fedora, but this experience have truly been hurtful. I cannot comprehend how this installer passed any quality checks.
