Re: [Duplicity-talk] duplicity +par2 hangs (or so it seems)

It seems that for some reason scp isn't working. I did a listing of the
duplicity processes:



address@hidden duplicity-0.7.12]$ ps aux|grep duplicity

 -rw------- 1 user user 209753903 May 13
22:33 /home/user/.temp/duplicity-uEnOe4-tempdir/mktemp-z2UoWG-2

address@hidden duplicity-0.7.12]$




So, to me it looks like it's trying to send a file via scp, but when I
look at the destination computer, then there's no file at all in the
specified directory:


address@hidden:/media/backupdrive/backup/duplicity/test1/rw $ ls -l
total 0
address@hidden:/media/backupdrive/backup/duplicity/test1/rw $


This has worked in my old duplicity however.
