I am trying to add the GPG key for one of my PPA to one of my pbuilders. Both the host and the pbuilder chroot are lucid. Here's what I do.

$ sudo pbuilder --login --save-after-login
[...] #pbuilder starts up
 # apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 15331454B72FD7EC

The second command was a desperate attempt to install the gpg key directly. The last command shows which packages are explicitly installed. My gut tells me there is a package missing in a normal pbuilder installation for this to work.
