[Duplicity-talk] duplicity 2.1.1 snap gnupg prompt

[address@hidden]

I have some unencrypted backups and with the latest release (snap) on 
Ubuntu 22.04, I am being asked for a GnuPG passphrase for decryption with 
all operations. I am supplying the --ssh-askpass and exporting the 
FTP_PASSWORD but the prompt keeps coming up.

Example operation (cleanup):

export FTP_PASSWORD="xxxxx" ; duplicity  --allow-source-mismatch --ssh-askpass 
--no-encryption  cleanup --force scp://user@ser.ver/etc

I get this output:

Local and Remote metadata are synchronized, no sync needed.

GnuPG passphrase for decryption:

"The GnuPG passphrase for decryption:" is unexpected and new.

If I change to sftp:// the only difference is the cache files get copied 
down again and the prompt for GnuPG comes up again.

 GnuPG passphrase for decryption:


Using pexpect+scp:// hangs with copying the signatures:

Synchronizing remote metadata to local cache...
Copying duplicity-full-signatures.20230825T044119Z.sigtar.gz to local cache.

Using pexpect+sftp:// copies down the cache files again - slowly, and then 
prompts again for GnuPG:

Copying 
duplicity-new-signatures.20230925T044123Z.to.20230926T044122Z.sigtar.gz to 
local cache.

Another question:
Is there a way to install the previous snap version (1.2.3)?

Thank you,
