I've been happily rolling along with my Deja-Dup backups to remote Google Drive for a month or so. At some point, I may or may not have entered a passphrase. I may or may not have had a GPG key at the time.

Recently, I put my home folder in source control, and somehow lost the .gnupg and .ssh folders. I got the latter back, but I'm not sure about the GPG, which I've only started using in recent months.

So, this week I enter a passphrase. Later, i get the following error in a dialog, each time.

Backup Failed

GPGError: GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: WARNING: "--no-use-agent" is an obsolete option - it has no effect
gpg: AES256 encrypted data
gpg: gcry_kdf_derive failed: Invalid data
gpg: encrypted with 1 passphrase
gpg: decryption failed: No secret key
===== End GnuPG log =====

I'm not sure if my backups are encrypted, or if there are backups with different passwords, or what. Running ps aux | grep duplicity yields the following, abbreviated command. Please note the last three arguments, gio..., no-encryption, & no-use-agent.

                 --no-encryption                                         \
                 --gpg-options=--no-use-agent                            \
                 ...

Please help me figure out if I have inaccessible backups and need to start over entirely. Thank you.
