Chris Lamb has a good Debian installation checklist, from which I stole most of this list.

   1 # Configure sudo, adding my user to the sudo group so I don't get password prompts
   2 apt install sudo
   3 adduser xjjk sudo
   4 echo '%sudo ALL=(ALL) NOPASSWD: ALL' > /etc/sudoers.d/No-Passwords-for-sudo-Group
   5 chmod 0440 /etc/sudoers.d/No-Passwords-for-sudo-Group

  10 # Configure locales to prevent harassment about it later
  11 apt install locales

  13 export LANG=en_US.UTF-8
  14 export LC_ALL=en_US.UTF-8
  15 locale-gen en_US.UTF-8
  16 dpkg-reconfigure -plow locales
  17 # …or install all locales so they don't need to be configured/reinstalled
  18 apt install locales-all
