* Story:

  After running 20180427 update and restart the computer, it showing the
message like on the attachment below for 1-2 seconds then computer restart,
again and again, just like bootloop.
  At first, i thought it was EFI problem. After i checked
http://mirrors.ustc.edu.cn/opensuse/tumbleweed/iso/Changes.20180427.txt that it
was update on shim, probably this was the caused.
  Through chroot, i tried to reinstall shim and based on
https://en.opensuse.org/openSUSE:UEFI, tried to follow "Booting the Machine
that supports only one signature with vendor provided Keys" part. But the
result was same.
  I have no idea about this error. Just backup my data and installing 42.3 for
a while.
