Forgot to say that if the ubuntu-keyring comes up as untrusted then
check your repository sources with

$ grep http /etc/apt/sources.list

This will give you a list looking something like

deb lucid main restricted
deb lucid-security main restricted
deb-src lucid-security main restricted
deb lucid-security universe
deb-src lucid-security universe
deb lucid-security multiverse
deb-src lucid-security multiverse

Unless you have reason to think that one of the sources in
sources.list is disreputable then you should simply accept the keyring
and install it. You have to trust the source of the keys to make other
packages trustable.

Good Luck
