You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Answer 1

Resolved the same.

Try

• to find out maria db installation in your ec2
• to remove it using yum remove mariadb-libs-1:5.5.41-2.el7_0.x86_64,

Then try again. It worked for me
