Ooops, no, sorry, it works (/tmp/a was missing). So the kernel is definitely able to mount the file systems, it's just that ecryptfs-utils and their key management do not work.

After the unsucessful attempt dmesg contains: [ 1265.695388] Could not find key with description: [<correct key ID>] [ 1265.695393] process_request_key_err: No key [ 1265.695394] Could not find valid key in user session keyring for sig specified in mount option: [<correct key ID>] [ 1265.695395] One or more global auth toks could not properly register; rc = [-2] [ 1265.695396] Error parsing options; rc = [-2] Note: The correct key ID has been replaced in the "<correct key ID>". 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. Add passphrase key to keyring 2. Add public key to keyring 3. Generate new public/private keypair 4. Exit Make selection: 4 host:~$ ls Private/ Access-Your-Private-Data.desktop README.txt host:~$ ecryptfs-mount-private host:~$ ls Private/ <ecryptfs content is present> To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ecryptfs-utils/+bug/1718658/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
