Can't run updates anymore, pop up saying: Requires installation of untrusted packages.

Asked by frank crull on 2013-10-15

I can't run updates anymore. After entering my password the up date manager shows a pop up saying: Requires installation of untrusted packages. The action would require the installation of packages from not authenticated sources. ??!

I have never had that before.

Are you able to assist?

I am trying to troubleshoot this issue because I have it. I don't understand what Anna Koukouraki is saying. I did the apt-get-update and at the end of the output it complains about several PPAs. I did the restore defaults, so the next thing is to reboot, but I don't understand at all what she says next. Can someone reparse?

I suppose I could now flood this message with crap from the command line:
