Hello,

Having some problems on a fresh full backup and collection-status before
and after deleting .cache/duplicity dir.
Tests are be doing with sftp backend.

% rm -r .cache/duplicity
rm: .cache/duplicity: No such file or directory
% duplicity full --ssh-askpass /home/FILES sftp://<SERVER>/duplicity-TEST2
Password for 'xxxxxxx':
Last full backup date: none
GnuPG passphrase for decryption:
Retype passphrase for decryption to confirm:

(duplicity-full.20251116T121147Z.manifest.gpg): GPG Failed, see log below:
===== Begin GnuPG log =====
gpg: AES256.CFB encrypted data
gpg: gcry_kdf_derive failed: Invalid data
gpg: encrypted with 1 passphrase
gpg: decryption failed: Bad session key
===== End GnuPG log =====

Any clues? I think same happens to restore cmd but I need more testing.

Thanks,
