Centos 6.7 Yum Nothing to do error
<p>My dedicated server is running on Centos 6.7
Yum does not seem to be working at all. Whichever package I try to install with Yum, does not work at all following No package "xyx" available and nothing to do error.</p>

<p>How do reset the whole yum to default.</p>

<p>I tried with </p>

<pre><code>yum update
</code></pre>

<p>and</p>

<pre><code>yum clean all
</code></pre>

<p>nothing works.</p>

<p>Example: when I try to install a package.</p>

<pre><code>root@ns321982 [~]# sudo yum install -y tigervnc-server
Setting up Install Process
No package tigervnc-server available.
Error: Nothing to do
root@ns321982 [~]# subscription-manager list
-bash: subscription-manager: command not found
root@ns321982 [~]# yum search tigervnc-server

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