I backed up from Ubuntu 16.04 to a USB hard drive using Deja-Dup. Following a system crash I tried to restore the data files to my new system drive running 18.04.
Deja-Dup offers a choice of backup locations including the USB drive as well as the option to choose a Local backup folder within that drive.
Either way, I get the error message,
Storage location not available with the explanation,
Waiting for Google to be configured in your backup settings....
I do not understand what Google has to do with a local, cabled connection. How can I recover the backed up files?
