I am out of ideas (distro-sync, downgrade, reinstall, etc)



Version-Release number of selected component (if applicable):
rtkit-0.11-19.fc29.x86_64 -> rtkit-0.11-20.fc29.x86_64 

How reproducible:
Every time

Steps to Reproduce:

For me that have two versions of rtkit:
1. dnf  erase rtkit-0.11-20.fc29.x86_64  # success

2. dnf -y upgrade rtkit # scriplet failed on 'rtkit-0.11.19'
(probably downgrade/upgrade also reproduce)


3. dnf list rtkit # show two versions of rtkit

Actual results:
Two conflicting versions of rtkit installed

Expected results:
rtkit upgrade without failures.


Additional info:

I am not sure if my system is corrupt. For example, running:

dnf list --showduplicates
