Debian Bullseye Bug Remedy Script

General Discussion

I have turned the instructions Debian Bullseye Bug causing Klipper to no longer find the printer board - #8 into a shell script: https://raw.githubusercontent.com/Sineos/useful_bits/main/Linux/fix_debian_udev.sh

It will:

  • Check if it is executed on Debian 11
  • Check if the installed udev contains the buggy version string
  • Check if run as root or under root rights
  • Update the system to the latest versions via apt update and apt upgrade
  • If Debian 11 AND buggy udev AND root is found, it will:
    • Check if the Debian 11 backports repository is already present → If not, download the repository signing key and install the repository
    • Install the fixed udev from the backports repository

Run it via

curl -sf -L https://raw.githubusercontent.com/Sineos/useful_bits/main/Linux/fix_debian_udev.sh | sudo bash

Above command will run the script as root
Only do this if you trust me or if you have verified the script beforehand.

Any tests would be appreciated. I did test it on various different OS versions, like MainsailOS, Pi OS lite etc.
