Ubuntu 22.04 Annoyances

Here are a few collected ways I like to customize Ubuntu 22.04 servers. I used to love Ubuntu, but I hate auto updates and snaps. They also put ads and other usless ads diguised as "news" in MOTD. ESM FUD is spread throughout the OS including simple apt functions. You do not need ESM and thus Ubuntu 22.04 has become super annoying. unattended-upgrade is an automatic installation of security (and other) upgrades without user intervention. Consider the ramifications of disabling this service.

Disable unattended upgrades

The Unattended Upgrades feature is enabled by default and it runs at system boot without the user's permission. The configuration is stored in /etc/apt/apt.conf.d/20auto-upgrades

Disable: sudo dpkg-reconfigure unattended-upgrades then a TUI will come up, select "No"

This will not permantently disable the function. After an update it will be enabled. In the file /etc/apt/apt.conf.d/20auto-upgrades change these values from 1 to 0. Even doing this it will

ChatGPT Telnet

Download the files into a directory.
Replace the API key with your own in gpt.js
Run npm i
Run node .
Connect to it using telnet

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

Use ESM yourself. (preferred)
Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
Stay on the existing version of the package until you can move to ESM.

How to unbrick an Amazon Kindle Paperwhite™

This guide instructs you in how to unbrick an Amazon Kindle Paperwhite. The consequences of following it are your own responsibility. This method (opening the Kindle and using the serial interface) should be a last resort and should only be considered if other methods fail

The Guide

Pry open Kindle using a prying tool
Unscrew the screen and remove it from the base. Note that there's a screw hidden under the adhesive at the top in the middle
Solder tin wire to serial ports on the bottom
Attach tin wire to USB TTY device (order is ground, RX, TX, from the kindle's perspective, where GND is the smallest pad) and plug USB TTY device into your computer
Open Putty on your computer in serial mode, with the serial port specified as your USB device and baud configured to 115200

The included script 'widevine-flash_armhf.sh' fetches a ChromeOS image for ARM and extracts the Widevine binary, saving it in a compressed archive. Since it downloads a fairly large file (2Gb+ on disk after download) it is recommended that you run the script on a machine that has plenty of disk space.

To install the resultant archive, issue the following on your ARM machine–after copying over the archive if needed:

sudo tar Cfx / widevine-flash-20200124_armhf.tgz

(Where 'widevine-flash-20200124_armhf.tgz' is updated to reflect the actual name of the created archive)
