And "zypper dup" works - installing zypper from Leap 15 on Leap 42.3 does not work - my understatnding from boo#1067737 and from current discussion is that breakage is not result of upgrading while using zypper but consequence of user meddling with upgrade process and trying to use binary from future release on old one.
What I see is that it broke because zypper depends on something that its real world dependency chain does not require be installed/upgraded along with it, one potential brokenness my (upgrade package management system first, then everything else) process used was intended to avoid. Broken zypper has never happened here in over three years of consistently using the (package management first script) process for both ordinary updates and distribution upgrades. August 2014 is earliest version I've been able to locate without unretiring old machines: #!/bin/sh zypper -v in zypper libzypp libsolv-tools rpm openSUSE-release zypper -v in device-mapper dmraid glibc lvm2 multipath-tools mdadm systemd udev -- "Wisdom is supreme; therefore get wisdom.
