I forgot to check the encryption box when installing linux, how to encrypt an already installed system?

Question

linux

During installation, I forgot to check the box, how can I encrypt the ENTIRE system now?

true/veracrypt do not support encryption of the whole linux system, you need a security option at the level of these options.

Answer 1

If this is not a server, then encrypt only the /home and swap partition (if any). Allows you to avoid a lot of gimoroy.
