That should fix it right up.

If you just want to add the one repository key generating the errors:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 437D05B5 3E5C1192
sudo apt-get update

Try opening Software Sources, go to the Authentication tab, and remove the keys for Extras and Ubuntu Archive. If you also see one for Security, remove that one as well.

Then run 'sudo apt-get update' again. You will get the authentication errors. Copy the numbers to the following command (you can use the full code rather than just the last 8 characters) and try adding them again.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys < add keys here >

I changed to the Norway server and the keys imported correctly for me, but if the above fails you might try changing servers from the Ubuntu Software tab.

thhe place where i should add the key, should i only add this:

 BADSIG 16126D3A3E5C1192 Ubuntu Extras Archive Automatic Signing Key

or only this:

 16126D3A3E5C1192

?

When you accomplished the earlier steps, did you also remove the key for Extras in the Authentication tab of Software Sources before running the above command? How you get to Software Sources depends on which release of Ubuntu you are using. If you don't know how to open it, just ask.
