Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

So I already installed Ubuntu on a Netbook I have, I have the system set up as a wifi router and I was planning on setting up other services as well. I did not set up disk encryption during install but I'd like to now but without having to reinstall everything, is this possible? If it is possible to encrypt my disk without needing to reinstall I also like to know how I could remotely decrypt it if I had to reboot via ssh.

Thank you in advance
