Issue
I'm on an Amazon Linux box:
# this command returns Amazon Linux AMI release 2018.03
cat /etc/system-release
When I try to sudo yum update, I get this output. I can't post the full output on SO but here is the part that bombs out:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
Does anyone know how I can repair my yum update command? Any pointers would be very helpful!
Solution
Aha, I needed to:
sudo yum remove epel-release
sudo yum update
