Installation of CentOS was uneventful; however, ABRT is listing problem which I'm having trouble deciphering:

ABRT has detected 4 problem(s). For more info run: abrt-cli list --since 1583853358

Can anyone lend some assistance to help me understand what this means?

MCELOG is now installed but isn't reporting any issues.

Thank you.

I used to intermittently get annoying messages from ABRT on Fedora - I have disabled it for years.
If those reports are now purely historical - say for the install - rm them from the cli tool. No more messages - go find some real problems to worry about.

It often occurs that the installation process causes errors to show up in the logs.
If the errors stopped occurring after the installation was complete, you can most likely safely ignore them. Just use the appropriate tool to acknowledge or delete the error.
