I have always been technically challenged, but it never stopped me from getting in over my head and making a mess. Now that I'm getting old it's only gotten worse.
Perhaps my dumbest screwup came last year, when I decided to erase the windows OS installed on an inexpensive desktop I bought, and install NixOS, even though I had only been regularly using linux for a year or two. I had laptops for years, so I hadn't seen a desktop for a while. I got a nice big monitor to watch my media, since I was away from home on an extended business trip and needed a source of entertainment. I got it installed after a few false starts, then started learning about the configuration.nix file. I immediately ran into trouble getting sound. I searched the web for a likely cause, tried different things, removed drivers, and quickly destroyed my configuration file. I learned all about Pulse Audio and PipeWire. I spent two days fuming over the problem. No Peaky Blinders. I reinstalled the OS twice. Then, out of the blue, it occurred to me that this wasn't a laptop with built in speakers. I went out and bought a cheap pair of speakers the next day. Problem solved.
Does anyone else have any stupid stories they are willing to share?
/etc/fstab
. I reliably mess up my booting every single time, and I have to recover it with the grub shell that I don't remember the syntax for.
