I wrote this down as I don't like having to install a handful of dependencies just to add a repository (PPA) on Ubuntu.

I used fish in my example.

Get the signing key URL

Open PPA Page (https://launchpad.net/~fish-shell/+archive/ubuntu/release-3 for example)
Click Tecnical details about this PPA (green writing)
Click the signing key link (this goes to https://keyserver.ubuntu.com/pks/lookup?fingerprint=on&op=index&search=0x88421E703EDC7AF54967DED473C9FCC9E2BB48DA)
Right click the link after sig cert and copy link (This copied link goes in the curl command to get the key)

If you want to prevent certain packages being accidentaly or purposely being removed, do this.

Example packages: nano and vim

Create a file: /etc/apt/apt.conf.d/protectedPackages

Place this into the file:

pkgCacheGen::ForceEssential {
 "nano";

	Commands to run

	# This will take a while:
	`gitlab-rails console`

	Then once you have the prompt `Feature.enable(:vscode_web_ide), run:
	`Feature.enable(:vscode_web_ide)`

	#!/bin/sh

	echo 'Updating repository data ...'
	apk update

	# List upgradeable packages into a temporary file
	apk list --upgradeable \| sed -e 's/{//g' -e 's/}//g' -e 's/]//g' > /tmp/apk-upgradeable

	# Add column headers
	echo 'Package,Installed Version,New Version' > /tmp/apk-upgradeable-final

	#!/usr/bin/sh
	# This script generates a list of urls domains monitored and checks their SSL expiry date

	cd /home/uptime-kuma/uptime-kuma/data

	if [ -f /tmp/ssl-check-data ];then rm /tmp/ssl-check-data;fi

	sqlite3 kuma.db 'select id from monitor_tls_info' > /tmp/ssl-check-data-IDs

	while read id

	LibreWolf by default closes all tabs unless they are pinned when you exit.

	`Settings > General > Open previous windows and tabs`
