Hi,
i'm using Ubuntu15.10 Desktop. (A few days ago, i was trying to use Ubuntu 12.04, 14.04). There's still one problem i couldn't solve for a while.
I can't use the openssl for ecryptfs.
I create a public/private keypair for ecryptfs using ecryptfs-manager. But there is nothing to select.
Sorta like this:
jasonxin@jasonxin ~ $ 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: 3
Select key type to use for newly created files:
Selection:

There should at least one option for me to select, sorta like this:

Make selection: 3
Select key type to use for newly created files:
    1. OpenSSL
    2. Probably some other option here
Selection:

AND

$ sudo mount -t ecryptfs ~/temp ~/temp
[sudo] password for redsandro:
Select key type to use for newly created files:
    1) openssl
    2) passphrase
    3) tspi
Selection:

But i've got like this:

$ sudo mount -t ecryptfs ~/temp ~/temp
[sudo] password for redsandro:
Passphrase:

So i'm confused about that. Am i missing something in installing ecryptfs-utils( i use my friends' computers for ecryptfs. Unfortunately ,the same questions happen over and over again. ).
