Comment 3 for bug 1770200

Error 'First patch in sequence [<duplicity.path.ROPath instance at
0x7f1b1a4927a0>] was a diff' patching <removed>.pdf

This is telling me that one of the difftar files is corrupted. A lot of disconnects and reconnects can indeed cause this problem.

Please do a full backup and verify. This should fix the problem. Also please note that a long string of incrementals is risky due to possible corruption in one item in the string.
