Ubuntu 18.04 installation with LUKS and LVM

Installation Process

Pre-installation from live OS

This setup of Ubuntu with LUKS and LVM is tested on Ubuntu 18.04.

Boot Ubuntu from a Live OS and select the option to try Ubuntu without installing. Follow the steps I've outlined below. Let's assume you're installing to /dev/nvme0n1.

Partition the drive with your tool of choice: I used gparted to set mine up.

Bootstrap the Synology DS215j with optware-ng

I tried the instructions described in the Blogpost Bootstrap DS215j to install optware for ds215j but was unsatisfied with the long outdated packages it provided. Luckily, there now is optware-ng which is a fork of optware and provides recent packages.

This is how I managed to install optware-ng on my Synology ds215j inspired by the instructions in the Gist Boostrap the Synology DS215j with optware, ipkg, and sudo:

Download & Install ipkg in a persistent manner

# become root

sudo -i

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
