How to install Ubuntu with LUKS Encryption on LVM

My work requires us to have full-disk encryption, so these are the steps I use.

The basic idea is to create a LUKS-encrypted partition which is used as an LVM Physical Volume.

The GRUB boot partition isn't encrypted, but everything else is.

These steps tested and working on 22.04 (jammy).

Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.

(Optional) Uninstall other versions of postgres

To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple.

dpkg -l | grep postgres
