There seems to be a problem with latest kwave package keeping it form installing:
Error:
Problem: cannot install both kwave-19.04.0-2.x86_64 and kwave-1:18.12.3-1.x86_64
- package kwave-19.04.0-2.x86_64 obsoletes kwave < 1:19.04.01-2 provided by kwave-1:18.12.3-1.x86_64
- cannot install the best update candidate for package lib64kwave18-1:18.12.3-2.x86_64
- cannot install the best update candidate for package kwave-1:18.12.3-2.x86_64
Users can upgrade other packages with this command:
$ sudo dnf clean all
$ sudo dnf --refresh --nobest --nogpgcheck upgrade
Post-edit: This is as fixed as it can be. If users see this error append --allowerasing to dnf command in use and that should remove offending package and install the latest version. For instance:
$ sudo dnf --refresh --allowerasing upgrade
