Comment # 1 on bug 1212899 from Andreas Stieger

This is not a distribution package, but a package from (apparently) the
Kernel:HEAD:Backport repository. Reporting bugs without context or reliable
steps to reproduce is just not acceptable. You most not assume that anyone can
read your screen or disk, and don't let others do the leg work.

In any case...

$ zypper ar --refresh --check
https://download.opensuse.org/repositories/Kernel:/HEAD:/Backport/standard/Kernel:HEAD:Backport.repo

$ zypper search -r Kernel_HEAD_Backport -s -t package --match-exact
