I am trying to add the GPG key for my "stable" PPA (https://launchpad.net/~r0lf/+archive/stable/) to one of my pbuilders This works fine outside the chroot but fails inside the pbuilder. Both the host and the pbuilder chroot are lucid. Here's what I do.
$ sudo pbuilder --login --save-after-login
[...] #pbuilder starts up

The second command was a desperate attempt to install the gpg key directly. The last command shows which packages are explicitly installed. My gut feeling tells me there is a package missing in a normal pbuilder installation for gpg to work and make a connection here, but of course, the problem could be elsewhere.
JFTR: The key exists of course on the keyserver in question. The apt-key command outside the pbuilder chroot works just fine. Try it!
Command in question run directly on the host:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 15331454B72FD7EC

I can't reproduce it.
As I didn't use my lucid pbuilder for some time, I updated it before I tried it (note: I use a precise host).
# apt-key adv --keyserver keyserver.
