Hello Cornelius,
Unless you need the personal package archive (ppa) that has been added to
your souces list, then you can remove them by either unselecting that
repository using Synaptic package manager or if you comfortable with the apt
configuration file you can edit /etc/apt/sources.list

If you do need the additonal packages in which ever personal package archive
you've added, then I suggest going back to the personal package archive
website on launchpad.  There are specific instructions on how to add the
repository (along with the public key - which is missing in your case) using
the command apt-add-repository ...

If you get stuck, please let us know which personal package archive you want
to use (send us the web address) and we can show you the relevant command.

Thank you.
