synaptic message after installing pclinuxos kde 2011.6

[molen]

After installing pclinuxos 2011.6 I get in synaptic the following message:
W: There are multiple versions of "libstdc++6" 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 { "^libstdc++6$"; };

To disable these warnings completely set:

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

etc...

What can I do with this message?

[menotu]

Do you have more than one repo selected molen

[Texstar]

run dupeclean from the menu under software center.

I have run dupeclean and got this message:

Is then the problem solved? I did not get any message in synaptic anymore.
Also another question: I have as source in synaptic:
http://debian.ethz.ch/mirror/pclinuxos/apt/pclinuxos/2010/main updates nonfree kde4 games. Is that the good source?

Yes, that's  fine molen

A couple of reasons that Synaptic may have problems can be that the mirror hadn't fully synced and/or more than one repo is being used which is a no-no (having the Megagames repo as a second repo is the exception to that rule)

It's often worth waiting for a few hours or mebbe switch to another repo (the heanet.ie repo in Ireleand receives a "good press" for reliability and speed)

from my location in the UK, I can +1 to the heanet repo.

solid speed, and so far very reliable 

other locations may vary.
