Please edit your question to add the output of cat /etc/apt/sources.list and for X in /etc/apt/sources.list.d/*; do echo; echo; echo "** $X:"; echo; cat $X; done -- this should shed light on whether or not you're using any software sources that might give you files from 13.04.

Installing Ubuntu 13.04 beta will cause this (or similar). Until actual release of 13.04 (in April 2013), the download is still labelled 12.10, but with a later kernel, new libraries, and other extras.

lsb_release gets its information from /etc/lsb-release, provided by package base-files, while gnome-control-center simply displays the PNG file at /usr/share/gnome-control-center/ui/UbuntuLogo.png, which is distributed in package gnome-control-center-data.

Check which gnome-control-center-data you are using with the following command:

apt-cache policy gnome-control-center

It may be a version from a PPA or some other source that you may have installed; depending on the outcome of the above command you may decide you want to purge the PPA, or reinstall the package, or ignore the reported version mismatch...

In any case, you seem to be running 12.10 with at least one file from 13.04.

The package is from ppa:gnome3-team/gnome3, not the quantal repositories. You can get it back to normal if you want by running sudo apt-get install ppa-purge and sudo ppa-purge ppa:gnome3-team/gnome3. Any updates from that PPA will be reverted - make sure that is what you want to do beforehand.

The only case I have here that shows like that is the 13.04 which is still in development (Ans also consider off-topic in Askubuntu):

If you installed some 13.04 packages (Either manually or via a PPA) it might have mixed the whole 12.10 with 13.04 packages and modified the System information to show the information as you see it now.

Yes, I'm sure I have the 12.10, definitly ! However as you said, it is surely some PPA from 13.04 that mixed the whole...I edited my post with some command output. Thank you for your answer.
