More like "oh shit, we are so screwed".

It's already a better system administrator than I am. It can run plenty of obscure linux commands, trash the system and maybe restore system state to functional.

I was vibe-setting my system permissions with some local qwen3.6 . It was all going well for 30 minutes.

Then in between other commands, it made me run a variant of "sudo chmod 644 /usr/bin"

Which it explained when the next command failed with a "sudo no such command" error removed the execution bit from all my programs which allows programs to be executed. And since sudo is a program, and sudo is needed to run chmod, the system was basically trash, and should be recovered from a live usb key.

So I booted to a live usb key, and followed its instructions. It really tried to recover, but everything went downhill. It always had a solution to everything, but every time the plan worked half way and trash the system even further. I let it play for four hours to see what it would try. Then I got bored (the LLM was running on an other machine and I was manually inputting the suggested commands each time). I took command and reinstall a fresh system over.

Of course once the fresh system Lubuntu24.04 was installed, linux had issues with the wireless network card drivers. So I turned to the LLM, and it managed to get the wifi stable enough via obscure modprobe options, so that I could update the system to the latest drivers.

Then it helped me re-parametrize the system to have the same look and feel as it had before.
