[Duplicity-talk] Duplicity errors upon attempted restoration from backup

Hi all,

I have been using duplicity to back up my Ubuntu 11.10 desktop PC to a Seagate external backup since August 2012. When I upgraded my system to Ubuntu 12.04, I lost my data files, and attempted to restore from backup using duplicity. Here's what I have tried so far;

1) Restore directly from external backup drive.
--Did not work. Error messages to the effect of 'no privileges.'

I transferred all backup files to the 1 TB hard drive, about 172 GB total. These are now in a directory called ~/duplicity2012.

2) Restore from System drive to alternate 500 GB hard drive.

I tried restoring to the hard drive without any restrictions, and restoring to a directory.
Received these error messages:

1/3/2013 – Duplicity failed to restore from backup – Errors
