Trying to mount a personnal dir (not home) with ecryptfs-simple fails, with the same error messages in kern.log as comment #20. (Using Linux Mint 19, Xfce.) The workaround in comments #26 and #30 works for me. (No sudo like in #28 : with sudo the mount works but the key sig gets added to /root/.ecryptfs . So keyctl has to be launched by thenormal user.)
This bug affects a cryptographic (read: highly sensitive) feature, is 15 months old, a patch was proposed 12 months ago, but it is still of "Undecided" importance and still "Unassigned"? Come on! Are the ecryptfs-utils and systemd packages unmaintained at Ubuntu? The maintainer of ecryptfs-utils, Dustin Kirkland, is only listed as "may be notified" in the list of subscribers! The group maintainer of systemd, "Ubuntu Developers", is not listed at all! ** Tags added: bionic -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1718658 Title: ecryptfs-mount-private fails to initialize ecryptfs keys Status in ecryptfs-utils package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: ecryptfs-mount-private fails to mount the ecryptfs after the 1st reboot after creating the ecryptfs by ecryptfs-setup-private.

I also accidentally found an workaround - just running ecrytpfs- manager and then the ecryptfs-mount-private (it does not ask for password for the second time and mounts the ecryptfs correctly): host:~$ ecryptfs-manager eCryptfs key management menu ------------------------------- 1.
