I found I had two .rpmnew files under /etc after the 7.6 update completed.
You may have more, fewer, or none.
This is just a suggestion to do the following at a root shell prompt:
Preformatted text# find /etc -type f -name ‘*rpmnew’
For each file found, compare it (using diff) with the corresponding file and decide how to proceed (ignore, adopt, merge).
