title: Error on Yum update
body: <p>I'm unfortunately not very experienced in CentOS administration, and was hoping someone might be able to help me understand and get past a small hurdle.  I was hoping to run yum update on the system, but ran into some Transaction Check Errors:</p>
  
  <pre><code>file /etc/php.ini from install of php55-common-5.5.11-1.el6.x86_64 conflicts with file from package php-common-5.3.3-40.el6_6.x86_64

  <p>It sort of looks like it's saying that some newer version files are conflicting with older version files.  Is there a standard way to fix this?  I was mainly just trying to update so that I could install Java later, but wasn't expecting to run into these errors.  If it helps, the server is mainly being used for hosting a few websites with apache and mysql.  Thanks so much for any help, it's greatly appreciated.</p>
  
  <p><strong>Edit</strong>:  To add some more clarification, I had previously edited the baseurl variable in the <strong>/etc/yum.repos.d/centalt.repo</strong> file, which was originally set to</p>
  
  <pre><code>baseurl=centos.alt.ru/repository/centos/6/$basearch
  </code></pre>
  
  <p>The reason I changed the location was because I was previously getting an error when trying to run yum update, mentioned in this other stackoverflow question <a href="https://unix.stackexchange.com/questions/132674/repository-metadata-repomd-xml-for-repository-mratwork-centalt">https://unix.stackexchange.com/questions/132674/repository-metadata-repomd-xml-for-repository-mratwork-centalt</a> which had an answer recommending replacing the URL with </p>
  
  <pre><code>baseurl=mirror.sysadminguide.net/centalt/repository/centos/6/$basearch
  </code></pre>
  
  <p>Is there a different url I should be using instead?</p>
