Ubuntu 16.04.02 | Deja-dup 34.2 | Restore keep asking "Encryption Password Needed"

Question

Please help..!

I already file a bug report in Launchpad. But I'm desperate to seek help, so I ask again here.

FYI. I never put password on my backed up files.

I made debug report as suggested here Deja-dup keeps asking for password. And below is the debug report
