duplicity hangs on hash mismatch

[Rikky]

duplicity 0.7.10 (also tried 0.7.12)
gpg (GnuPG) 2.1.15 (also tried 2.1.20)
Python 2.7.12
OS Ubuntu 16.10

When trying to restore a backup I get something like this:

Invalid data - SHA1 hash mismatch for file:
 duplicity-inc.20140206T204751Z.to.20170422T212414Z.vol564.difftar.gpg
 Calculated hash: 50260e392c2fe2921c614d5e0ccaf2d269b671f8
 Manifest hash: 22b89cd6256efec29158b801737ada6b83c18e89

After this message, duplicity just hangs. Adding parameter "--ignore-errors" makes no difference. Would be nice if it would continue restoring the data.

You can backup the manifest file and then use a text editor to change the Manifest hash to the Calculated hash and retry again. You'll probably need the --ignore-errors option.
