I have a problem with the software on my OS, maybe It's a disease, I don't know. The reason:

If you want to run a script for example, after apt update on Debian, you can use the apt hook system. This is useful if you want to perform some other action after the update. In my case, I need to run a script and re-install the Vulkan driver on Raspberry Pi, because apt update break it and the system can't open the Desktop environment.
