Checkn1x is a minimal, stripped-down Linux distribution (based on Alpine Linux) designed to do one thing and one thing only: run the checkm8 bootrom exploit on iOS devices.
The file in question, checkn1x-1.0.6-amd64.iso, represents a specific stable release (version 1.0.6) built for 64-bit x86 architecture (AMD64). Unlike full desktop Linux distributions (Ubuntu, Fedora, Arch), Checkn1x boots directly into a command-line interface pre-loaded with palera1n – the most prominent jailbreak tool for checkm8-vulnerable devices. checkn1x-1.0.6-amd64.iso

Verdict: If you own an iPhone X on iOS 16 (which is not possible – iPhone X max iOS is 16.7.10), wait—correction: The iPhone X caps at iOS 16.7.10, and checkm8 works there. checkn1x is the only way to jailbreak iOS 16 on an iPhone X.
Do not search for "checkn1x-1.0.6-amd64.iso download" on random forums. Always use the official GitHub repository of the checkn1x maintainer (the project is a fork of the original checkra1n Linux build). As of this writing, the legitimate source is checkn1x GitHub releases.
The A11 chip (iPhone 8, 8 Plus, iPhone X) has a caveat: you must disable the passcode before jailbreaking for the exploit to work reliably. checkn1x-1.0.6 clearly warns you about this before execution.
