OpenPGP V2 card and Ubuntu Karmic Koala
If you’re trying to get it to work on Jaunty or Debian, I’m sorry to have to disappoint you, but I’ve not been able to get that to work properly. If you have, please let us know in the comments below.
The key is using gnupg 2.0.12 (with the Ubuntu patches) and installing libccid, which seems not to be pulled in by default. After that, it’ll work as expected. We’ve been using a SCM SCR335 to attach it to the computer, but any other supported smartcard reader should work.
We spent a whole day on this, trying to get it to work. I don’t get why kernelconcepts already sells these exclusively if the support in GnuPG is still so fresh. Bit of a shame.
Error we got were things like:
scdaemon[85270]: updating slot 0 status: 0x0000->0x0000 (0->1)
scdaemon[85270]: sending signal 31 to client 85269
and:
gpg: key operation not possible: Unknown IPC command
Hope this helps someone!
