  <p>However, I'm having problems installing MariaDB in a Cent OS 7 machine. I run </p>
  
  <pre><code>$ sudo yum install mariadb-server
  </code></pre>
  
  <p>and this is the output I get:</p>

   You could try using --skip-broken to work around the problem
   You could try running: rpm -Va --nofiles --nodigest
  </code></pre>
  
  <p>I already tried to run </p>
  
  <pre><code>sudo yum install mariadb-server --skip-broken
  </code></pre>
  
  <p>and</p>
  
  <pre><code>rpm -Va --nofiles --nodigest
  </code></pre>
  
  <p>with no luck. Any suggestions? </p>
