I have installed Ubuntu Server 16.10 Set up disk encryption with passphrase and installation on whole disk. Now every start or reboot is asking for
Please unlock disk sda5_crypt
Is it possible to run the server encrypted without entering the passphrase every time? I am scared of somebody stealing the server with data. But I need the server to work after reboot too.
Is there a solution for this? Is it necessary to enter the passphrase after reboot or can the system work without it?
