Don't normally have problems with regular upgrades but on my latest upgrade i got a "Requires installation of untrusted packakes" or some such. The offending package seems to be "libnatpmp1"
Any help appreciated.

follow the ppas procedure to get them signed
that lib might come from one of them

I've been googling around and solved the problem in the following manner...

"cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get update

This will rebuild the cache."

For the benefit of others.
