Ubuntu 20.04 Server Edition Rescue Tips
When Things Go Horribly Wrong

Updated 28 July 2021

To err is human;
to really foul things up requires a computer.
  — Bill Vaughn

People make mistakes. It happens. Lord knows I made quite a number of them in my trek to build a gaggle of servers. This page describes techniques I learned the hard way to recover from my blunders without having to start the server build all over again. (But sometimes, it's a shorter path to start from scratch, because the effort to effect a rescue can take longer than dumping and going again.)

Comments, suggestions, and error reports are welcome.
