Déjà Dup

Failed with unknown error

Asked by Esau B.

Hello.

Running Ubuntu 9.10 with kernel 2.6.31-20. Gnome 2.28.1. Both my hard drive and the external drive i'm trying to save to are formatted with ext3.

I'm trying to run Deja Dup and keep getting this error:

Traceback (most recent call last):
  File "/usr/bin/duplicity", line 825, in <module>
    with_tempdir(main)

    result = open(self.name, mode)
IOError: [Errno 13] Permission denied: '/media/Backup/duplicity-full.20100213T044734Z.vol1.difftar.gz'

Any help would be appreciated.

This sounds like your user doesn't have permission to write to the external drive? Can your user create folders on the drive through nautilus?

Ext3 can be a bit picky about permissions. If you're unsure how to mount it so that your user can write to it, maybe use fat/ntfs which is far less picky? :)

Though, I agree the error message could be nicer. I *think* it is in the latest versions, but I will have to check.

Can you help with this problem?
