Comment # 1 on bug 1208547 from Stefan Hundhammer

This is clearly not a problem of the installer; even more so since you didn not
even use it. You used "zypper dup", so there is a slim chance that it might be
a zypp problem (Bugzilla component libzypp).

But much more likely, this is a problem of the affected packages; either
update-alternatives (not very likely) or python3.
