Once the previous fedup command is complete, reboot the server (the command will tell you):
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px; text-align: left">
sudo rebootshutdown -r now
</div>
The actual upgrade will take place now, so you will not be able to access the server (or the network) until it is complete.
Once the upgrade is complete, from the command line execute:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px; text-align: left">
sudo yum syum check
</div>
The following message or similar will be displayed:
To correct these issues, remove the two bad packages (though this could be dangerous if you had a lot of apps installed (in which case we do not recommend it):
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px; text-align: left">
sudo yum remove perl-PlRPC-0.2020-13.fc19.noarch ruby-mysql.x86_64
</div>
Ensure all the problems are corrected and execute:
<div style="border: 1px solid #A3B1BF; padding: .5em 1em; color: #000; background-color: #E6F2FF; margin: 3px 3px 1em 3px; text-align: left">
sudo yum check
</div>
The response should be <code>check all</code> which indicates everything is correct.
