Thanks for your comment. I did not installed anything myself regarding Deja Dup. I made a fresh installation and clicked the Button in the GUI. Although I kept the old Home partition from 14.04. So it might be a problem related to this? Although the setup there is working so that is not the problem.
Regarding the problem: I made an installation of 14.04 (on hardware not inside of a virtual machine), set up a backup on an external hard drive, installed 16.04 while keeping the home partition and found out, that a backup is triggered by plugging in the hard drive, which results in the mentioned error. So it is *not* necessary, to use the command line to trigger this.
We (or better Michael) should add the check to the code, which triggers the Backup, if the location comes available. I do not figured out, which location this is, because I am busy with bug #918489.
