Hi,
I had encrypted backups working fine for weeks on a server. As the encryption uses the public key, it doesn't ask for a password.
Then I did a duplicity verify, which requires the gpg private key, and asks for a password.
The verify went fine, but since then the gpg key password is also asked for backups, preventing the automation.... I'm nearly sure this is linked
I have removed the duplicity cache in ~/.cache/duplicity, but to no avail....
