Question

linux

Guys, help with the decision!
Worth Fedora 21
After entering, yum update
700 meters of updates are tightened.
Apparently, along with it, a 32-bit environment was delayed.
Attention question!
How painlessly for 64 bits to delete 32nd environment?

Answer 1

apparently it dragged on with him

It can't drag itself out unnecessarily.
rpm -qa --last will show you which packages were installed last.
The simplest test: rpm -qi glibc -- will give you either one or two glibcs.
yum remove '*.i686'
