Re: [Duplicity-talk] backing up using SFTP to a directory under my home directory

[Luis Tirado]

Hi Scott/Edgar,

Switching to the default paramiko worked, had to end up installing
that module instead and changing to the default sftp:// that uses it
with the added / worked to access the correct path. For whatever
reason pexpect+sftp did not like the // syntax. Working smoothly now,
thanks!
