I came across an old openSUSE Tumbleweed virtual machine image. It still booted in KVM/Qemu. When it started I noticed it was from 2018. So I tried to update it (I had to install the correct repositories) and when I did

# zypper dup

this is what I saw:

After a long time, the update was NOT successful. Of course. There was a dependency hell of cpio not able to extract packages, rpm, zypper ,libzypp and several others (all the way to numerous python modules) that I simply could not solve. Bummer!
