My Linux experience

I got excited when I had my Operating System paper during my second year at college. I wanted to try out the Linux Operating system(Ubuntu), So I just dual-booted Ubuntu along with windows. it was pretty much normal. until today, I accidentally uninstalled the built-in python3 installation using the 'sudo apt autoremove python3' command. It was a nightmare since it removed the GUI of the entire system and got a CLI version as my interaction with the OS. It took me several hours to figure out what I'd made and finally, I realized that my command previously executed had just removed the Graphical display manager which was 'gdm3' in ubuntu. This incident made me feel more confident that I can solve more issues. It was a nice time, playing with Linux, I'm going to use it as my daily driver.
