Sorry, this will not work. This is already better, but: - Which system did you start from? openSUSE 15.0 or some (and which) earlier version? Or some (and which) non-SUSE system? - There is more than one way to start an upgrade with openSUSE. Which exact commands and/or mouseclicks did you use? - Even for openSUSE 15.1 beta, there are several ways to install the system. If you suspect that you got a wrong URL, you could go back (starting with some system including a functioning X11 or even Windows installation and a functioning GUI browser) to the place where all these various methods start from, namely https://software.opensuse.org/distributions/testing . If you choose to do that, please tell us where you went from there.
