Leap 15.6 image respin ( news.opensuse.org )
Leap 15.6 install media were refreshed to address an issue with old secure boot signing key for ppc64le and s390x.
Refreshed images from Leap 15.6 Build 710.3 are already available for download at get.opensuse.org. So now you can enjoy installation with secure boot on more exotic architectures.
Happy Hacking!
