Changing the value from "Volume" to "Normal" fixed the problem for me as well (https://bugs.launchpad.net/deja-dup/+bug/539393/comments/6).
Just out of curiosity, what caused this bug to appear? I don't remember any deja-dup update, but this bug appeared on both of my computers about 2 weeks or so ago. It is true that I changed the backup destination folder to external drive on the computer #1, but I haven't changed anything on computer #2, but this bug appeared there well. -- deja-dup fails on backup to external drive with g_file_get_uri: assertion `G_IS_FILE (file)' failed https://bugs.launchpad.net/bugs/569418 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
