W: There are multiple versions of "curl" in your system.

This package won't be cleanly updated, unless you leave
only one version. To leave multiple versions installed,
you may remove that warning by setting the following
option in your configuration file:

RPM::Allow-Duplicated { "^curl$"; };

To disable these warnings completely set:

RPM::Allow-Duplicated-Warning "false";

W: You may want to run apt-get update to correct these problems

Can someone tell me how to uninstall one of the versions of curl so I don't get this error when I run apt-get?

Thanks.
