I already have the ownership of that folder, so that does not seem to be the problem for me. I did, however, try activating deja-dup logs like you did. I have attached the last bit of the output. «krypterte data» means «encrypted data», and «dekryptering mislyktes: ugyldig pakke» means «decryption failed: invalid package». The error messages are to vague for me to interpret in a meaningful way.
I have just made a fresh install of Ubuntu, and I really thought that would fix the problem. ** Attachment added: "deja-dup bug output" https://bugs.launchpad.net/ubuntu/+source/deja-dup/+bug/989750/+attachment/4269238/+files/deja-dup%20bug%20output -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to deja-dup in Ubuntu. https://bugs.launchpad.net/bugs/989750 Title: repeatedly asks for encryption password when backing up, even though "remember password" is ticked Status in “deja-dup” package in Ubuntu: Confirmed Bug description: I've set deja-dup to back up automatically, and to encrypt files. But it never gets far: every few seconds, it brings up a "password needed" window somewhere out of sight (behind other windows; but that is another problem/feature), even though I've told it to remember the password. So using this backup software seems entirely impractical; it will never finish.
