What is this error after updating 16.1 beta

%posttrans(sg3_utils-1.48+37.9d1e80e4-160099.1.1.x86_64) script output:

Do you have the 32bit compatibility package grub2-compat-ia32 installed?

As Leap 16.x is 64bit only until you install the named compat package, pure 32bit libraries will throw an exec format error.

I haven’t installed anything specifically, but I do remember while upgrading to 16.1 beta via migration-tool it asked me at the end that do I want 32 bit compatiability for something and then (steam) so I checked it, thats all… but everythings working fine after that error also…
