You're doing it correctly with the GPG key.

Debian Etch is using a rather ancient version of duplicity, 0.4.10.  The
latest version, 0.5.03, is available at http://www.nongnu.org/duplicity
and I would suggest you upgrade to that.  There have been a lot of fixes
in the interim.

Also, it might be a good idea to run a 'duplicity cleanup' prior to
running since you have incomplete backup sets.
