Q: duplicity works fine when run standalone, but complains about gpg
|
|
"public key not found" when run from backupninja
|
|
|
|
A: We bet you're using sudo to run both duplicity and backupninja, and have been
|
|
using sudo as well when generating the GnuPG key pair used by duplicity.
|
|
|
|
Quick fix: generate a new GnuPG key pair in a root shell, or using
|
|
"sudo -H" instead of plain sudo.
|
|
|
|
Another solution: import the GnuPG keypair into the root user's keyring, taking
|
|
care of running "gpg --update-trustdb" in a root shell or using "sudo -H"
|
|
afterwards, in order to tag this keypair as "ultimately trusted".
|
|
|
|
Detailed explanation: sudo does not change $HOME by default, so GnuPG saved the
|
|
newly generated key pair to your own keyring, rather than to the root user's
|
|
keyring. Running "sudo duplicity" hides the problem, as it uses your own
|
|
keyring. Running "sudo backupninja" reveals the problem, as backupninja uses
|
|
"su" to make sure it runs duplicity in a real root environment, i.e. using the
|
|
root user's GnuPG keyring.
