Duplicity cleanup

Hello there, our backup reports errors.

Warning, incomplete backup sets were found, probably left behind by an aborted session
/tmp/duplicity-oVPYI_-tempdir/mktemp-Lqpus1-2 could not be read: (<type ‘exceptions.IOError’>, IOError(‘CRC check failed 0x8e20dfcf != 0xe945bef9L’,), <traceback object at 0x7f0015ebaa28>)
Duplicity backup failed
Action ‘backup-data-duplicity backupneth’: FAIL
Backup status: FAIL

After a lot of research I found that a cleanup was necessary:
duplicity cleanup --force
, in my case for example:
duplicity cleanup --force file:// .

Unfortunately I am then asked for a GnuPG passphrase. Is that the share password?

On Nethserver Duplicity is configured to not encrypt backups.
Have you tried filling in a blank password or to use the command but adding --no-encryption parameter?
If it does not work, please post the command output that is requesting gpg.

I tested it out: it’s the share - password. Thank you.
