[Duplicity-talk] Verification failing

[mjs]

I have duplicity setup to sign and encrypt backups.  Verification is
failing for full and incremental backups with the following error:

Volume was signed by key XXXXXXXX, not YYYYYYYY

I use the same script for both full and incremental scripts.  Below are
the backup commands for full and incremental as well as for verification. 
The odd part is that the verification says the backups were signed by the
public key.  Also odd that the verification process hangs after the
incremental backups but finishes executing for full backups.  Verification

sign_key="YYYYYYYY"
pub_key="XXXXXXXX"

# Full backup
$duplicity $backup_type -v9 --include-globbing-filelist
inclusion_filters.txt --ssh-options="-oProtocol=2 -oIdentityFile=$ssh_key"
--sign-key "$sign_key" --encrypt-key "$pub_key" /
scp://address@hidden/$backup_path > $log_path

# Incremental backup
$duplicity $backup_type -v9 --include-globbing-filelist
inclusion_filters.txt --ssh-options="-oProtocol=2 -oIdentityFile=$ssh_key"
--sign-key "$sign_key" --encrypt-key "$pub_key" /
scp://address@hidden/$backup_path > $log_path

# Verification
$duplicity verify -v9 --include-globbing-filelist inclusion_filters.txt
--ssh-options="-oProtocol=2 -oIdentityFile=$ssh_key" --sign-key
"$sign_key" --encrypt-key "$pub_key"
scp://address@hidden/$backup_path / >> $log_path


Any ideas?

Thank you for your time
