[Duplicity-talk] Restore breaks part-way with KeyError 131072

[Simon Blandford]

I am restoring a backup and, after restoring some of the files, I get

KeyError: 'GnuPG exited non-zero, with code 131072'

The last full backup was in July and weekly incremental backups have 
been taking place since. There is only one error reported in the log of 
duplicity output during the backups. This may not be relevant but I am 
pasting it at the end of the email.

The command I am using to restore is
duplicity restore --encrypt-key=123456 --gpg-options 
--homedir=/opt/s3backup/.gnupg --log-file=/mnt/duplicity.log 
--num-retries=5 --file-to-restore=var/www/html s3+http://my.bucked.name 
/mnt/html



The full trackback:

Error reported in backup log with next run after the error:
