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">
syum yum 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">
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">
yum check
</div>
The response should be <code>check all</code> which indicates everything is correct.
