Hi, I'm on 20210524 and just ran zypper dup, the merge went badly. Every other package update started failing because it could not find /bin/sh or other binaries for the pre/post install scripts, I basically couldn't launch any program, only the terminal I had already open worked. Looking at the filesystem /bin was indeed linked to usr/bin and I could find /bin/sh, /bin/bash and others but for some reason no program could. After reboot the GUI wouldn't start, logging in also didn't work because the system couldn't find a shell. Luckily snapshots work great and I returned to a working system in a few minutes. Any thoughts? I could try running dup again tomorrow but if it messes up again I'd need some tips on what to look for to figure out why it happened.
