using usb install media with 15.6 RC .iso file, booting up into upgrade mode and letting it upgrade, selects 8 packages only and about 200megabytes or such and installs along at the end when saving settings and bootloader stuff, it fails apparently with the same errors as in zypper logs given, that it cannot complete suse mkinitrd or something methinks. something like that. this didnt help. dunno whats wrong here the 15.5 was working a long time fine also kernel updates and opensuse patches via zypper up and all. maybe i try a fresh 15.5 and upgrade that to 15.6rc on this hardware? cant be that buggy? p.s. i have had 15.6rc installing normally fresh into a virtualbox simple setup though.
