Error: Transaction check error:
file /usr/bin/debuginfo-install conflicts between attempted installs of yum-utils-1.1.31-513.fc27.noarch and dnf-utils-2.1.5-1.fc27.noarch
I got around this by removing yum-utils. It then allowed me to move on to the upgrade. Got this idea from similar threads online. Hoping anyone that runs into this after me will find this useful.
Here's to hoping the jump from 23 to 25 will be as significant as the one from 25 to 27.
