After update from openSUSE Leap 15.1 to Leap 15.2 I cannot install the amdgpu-pro driver requred for my Athlon 3000G. On my system UEFI/secure boot is enabled. I've downloaded the latest 20.30 release ( https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-30 ) unified Linux driver explicitly suitable for SLES/SLED15PS2 (equivalent to SLES/SLED 15SP2).
Initially, zypper / yast won't accept unsigned rpms, both with addition of the driver rpms via the local repository method and the direct method using the amdgpu-pro-install script.
Additionally, starting with Leap 15.2 kernel modules are no longer accepted in secure boot mode ( https://doc.opensuse.org/release-notes/x86_64/openSUSE/Leap/15.2/, section 4.1 ) .
Is there any chance to obtain/ship officially signed rpms? Disabling secure boot on UEFI systems, or reverting to legacy boot cannot be the final solution.
