Why can Déjà Dup not complete the backup of .cache/dconf and .gvfs?

I'm 24hrs into using Déjà Dup. All seems well apart from this error message:

Backup Finished

Could not back up the following files. Please make sure you are able to open them.

/home/mjwittering/.cache/dconf

/home/mjwittering/.gvfs

What should I do, if anything?

Solution 1:

I've been able to solve my question after finding this web page. You need to update the owner and group for each file which is failing to backup. I used these commands to solve the situation.

sudo chown mjwittering .cache/dconf .gvfs
sudo chgrp mjwittering .cache/dconf .gvfs

Then run the backup again, which should now complete successfully.
