Simple shell script to make TmaxOS "usable" (But It doesn't make garbage less stinky)

jotmax2usable.sh

#!/bin/bash

echo "Add Debian Sources.list"
sudo echo "deb http://ftp.kr.debian.org/debian/ stable main contrib non-free" >> /etc/apt/sources.list
sudo echo "deb-src http://ftp.kr.debian.org/debian/ stable main contrib non-free" >> /etc/apt/sources.list
sudo apt update
sudo apt upgrade -y

sudo apt install dh-python
sudo apt install -f

echo "Fix garbage language pack"
sudo apt install locales
sudo dpkg-reconfigure locales

echo "Log out and Log back in"
