I would like to encrypt my system drive, how can I do that?

Question

Encryption

I had a need to encrypt the system disk, but I'm used to Windows encryption where full system encryption with a password (I used VeraCrypt), but I never found information about full encryption, and then I thought about encrypting one disk, maybe I'm stupid but I didn’t understand much about LUKS and what guides I didn’t read everything about the crypto-container.

So to the point, how can you encrypt a disk system on UBUNTU?

Answer 1

cryptsetup luksFormat

Answer 2

Most distributions have a disk encryption option during installation, just use this option during the installation phase.

Answer 3

Full disk encryption after installation is no longer possible.
You can encrypt the user folder after installation something like this:
