[Duplicity-talk] Completely broken the backup process when upgraded to 0.6.20 ([Errno 104] Connection reset by peer)

[howard chen]

We are using 0.6.1 and updated to 0.6.20 and the backup process failed completely,

with the error (without -v)

Local and Remote metadata are synchronized, no sync needed.

Last full backup left a partial set, restarting.

Last full backup date: Thu Nov 15 07:10:08 2012

RESTART: The first volume failed to upload before termination.

         Restart is impossible...starting backup from beginning.

Local and Remote metadata are synchronized, no sync needed.

Last full backup date: none

Last full backup is too old, forcing full backup

The backup is definitely okay before the upgrade. 

Any idea?
