[Duplicity-talk] gpg "no public key", but only when run from cron

[Steve Madsen]

I'm having a bear of a time getting my automated backups to work  
properly from the cron environment.  I am using the scp transport.   
When run interactively, it works fine.  When run from cron, I get this  
error:

gpg: 2D2CF1CB: skipped: No public key
gpg: [stdin]: encryption failed: No public key

I think my keys are set up OK in GPG:

cheechoo# gpg -k
/root/.gnupg/pubring.gpg

I had previous problems with "Fatal Error: Neither remote nor local  
manifest is readable" (fixed by adding --archive-dir) and PATH  
differences in the cron environment, but those are all resolved and  
I'm down to this GPG issue.

Anyone have any ideas?
