These are the bunch of overengineered scripts that allow me to take an old Ubuntu laptop's backup, take the important user data from it, migrate that to Linux Mint and unsnappify it without interrupting use of the old laptop, and then prepare it so it will run a proper setup wizard on first boot to set up the new laptop that will run the copy of Linux Mint in the end.

For this purpose, I set up:

The old laptop - The old Linux install machine, in my case an old Acer Aspire E5 with Ubuntu 22 on it. Runs Veeam Agent for Linux, backs up to NAS.
A hypervisor - I will use VMs to do a migration of data from the old laptop to Linux Mint without interrupting work on the actual device. In this case, I used Proxmox. It hosts:
- VM 1 (source VM) - Holds the files of the old laptop from the Veeam backups on NAS so the Linux Mint VM can migrate the important parts over via SFTP. A backup restore script runs regularly.
VM 2 (Linux Mint VM) - Runs a copy of Linux Mint that will be sysprepped. A separate disk hold

youtube-dl has the ability to give you a direct download link for a video instead of downloading the whole video by itself. This is really useful if you only intend to clip a specific part of a stream, and you can even do that without reencoding for maximum speed if you can accept a tolerance of 2 seconds (the usual keyframe interval used for streams). This is a technique I am using to make my Games Done Quick clips as well, so this is not limited to YouTube.

Here's how you can do it:

Requirements

youtube-dl, ideally newest version (https://youtube-dl.org)
ffmpeg, you can get this from https://ffmpeg.org/download.html.
- ready Windows binaries: https://www.gyan.dev/ffmpeg/builds/#release-section
For protected streams you may need to pass cookies to youtube-dl and a tool to generate the cookie file for it, see below for details.

Arch Linux (and I assume several other mostly-as-is distros) currently ships a broken version of the ssh-copy-id script with their openssh package because the upstream developers decided to merge a "ported" version of the script by Phil Hands back into upstream. While it contains many improvements it does reintroduce the error messages and changes actually not taking any effect in authorized_keys.

It turns out getting the new script back running is pretty simple with the changes listed below.

I suggest copying the original script from /usr/bin/ssh-copy-id to a new folder that you prepend to your $PATH (like $HOME/.local/bin) and then applying the patch listed here. This way the copy will take effect in $PATH searches until the issue is resolved so you can safely delete the file.
