How to Encrypt Your Home Directory on Ubuntu 22.04

Encryption is a process of transforming data into an unreadable form that can only be accessed by authorized parties. Encryption can protect your personal and sensitive information from unauthorized access, theft, or tampering. One of the ways to encrypt your data on Ubuntu is to encrypt your home directory, which is where your personal files and settings are stored.

This gist will describe how to encrypt your home directory on Ubuntu 22.04 after installation. This method is useful if you have already installed Ubuntu without encryption and want to add it later. It will also work on other versions of Ubuntu that use the ecryptfs-utils package for encryption.

Backup Your Data

Please make sure you have created a backup of your system/files before proceeding with the encryption process. This process may involve significant changes to your system, and having a backup ensures that you can restore your data in case of any unexpected issues during the encr

### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places. 
###.   Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of 
###.   things to watch out for:
###      - Check out the `nix-darwin` instructions, as they have changed.
###      - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026

# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.

Install

sudo apt-get install xclip -y

Create Alias

alias pbcopy='xclip -selection clipboard'
alias pbpaste='xclip -selection clipboard -o'

Try out

javascript:(function() {

function copyToClipboard(text) {
    if (window.clipboardData && window.clipboardData.setData) {
        /*IE specific code path to prevent textarea being shown while dialog is visible.*/
        return clipboardData.setData("Text", text); 

    } else if (document.queryCommandSupported && document.queryCommandSupported("copy")) {
        var textarea = document.createElement("textarea");
        textarea.textContent = text;

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

1. List All System Images Available for Download: sdkmanager --list | grep system-images

2. Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"
