I faced the same issue after upgrading from Ubuntu 17.04 to 17.10 a day ago. I'm having my home directory encrypted and I'm getting the same error message after every first login. My home directory is mounted correctly though.
As an even worst consequense I'm not able to login into grafical environment at all: Gnome keeps crashing when I click on my user name (I even do not have a chance to enter password). Not sure, however, if this is related to the encryption issue; I'm still checking. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1718658 Title: ecryptfs-mount-private fails to initialize ecryptfs keys To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/1718658/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
