I installed Leap 42.2 from a USB flash drive as a new install on a Dell x86_64 workstation. I have been doing “zypper refresh” without problems until today. Suddenly I get
% sudo zypper refresh
Repository 'openSUSE-Leap-42.2-Non-Oss' is up to date.
Repository 'openSUSE-Leap-42.2-Oss' is up to date.

% zypper lr
Repository priorities are without effect. All enabled repositories share the same priority.

What is the repository list supposed to be, and why did a from-scratch install give me a non-working repository list? And why did it work at first and then break?
