The problem gets triggered via texlive-filesystem that has only a "Requires: python". Because python3 has a "Provides: python" it gets installed. Unfortunately python3 has no link/binary called python.
One way to fix this is a seperate "Requires(pre): /usr/bin/python" inside the texlive-filesystem.spec file.
I'd like to know why this has become a TeXLive bug. If python3 provides python3 then it should provide /usr/bin/python ... that looks like a simple approach of update-alternatives here -- You are receiving this mail because: You are on the CC list for the bug.

Using update-alternatives for python would be perfect (also for ruby that suffers the same kind of issues). We had some discussions about the hole python/python3 situation on the mailing list: https://lists.opensuse.org/opensuse-factory/2017-06/msg00740.html Adding Tomas as the python maintainer. -- You are receiving this mail because: You are on the CC list for the bug.

The provides python is done for migration purposes only and should still let you keep the old python2. -- You are receiving this mail because: You are on the CC list for the bug.

But nonethless: this won't change for leap 42.3 as it would open the too big can of worms. For 42.3 the only option is changing the require in texlive to /usr/bin/python - for tumbleweed I think these scripts are already gone? If not, using /usr/bin/python3 in the script and as require is the road to go. -- You are receiving this mail because: You are on the CC list for the bug.

There are gone ... nevertheless providing "python" without /usr/bin/python is a bug IMHO -- You are receiving this mail because: You are on the CC list for the bug.

Why would this approach result in compatibility problems? Users that install python3 + pip on a system where they have python2 already will have a totally messed up environment. /usr/bin/python -> python2.7 /usr/bin/pip -> /etc/alternatives/pip -> /usr/bin/pip3.4 So it is also my opinion that this is a bug. -- You are receiving this mail because: You are on the CC list for the bug.
