Re: [Duplicity-talk] Error using launchd with duplicity

[Kenneth Loafman]

There is a fix for this in the upcoming release.  For now, in
backends.py, change line 432 from:
        child.sendeof()
to:
        child.sendline('quit')
and make sure that the passwords are supplied in the environment.

...Thanks,
...Ken
