I used the procedure given at https://askubuntu.com/questions/793135/how-to-restore-a-broken-deja-dup-backup-manually. I was able to recover files from backup but not the latest incremental; which gave the same error as above 'Bad session key' on the latest incremental files. My password was correct for the first full backup and the first incremental but seems to fail on the second and last incremental.
