Fonts on Linux (Ubuntu): see https://askubuntu.com/questions/3697/how-do-i-install-fonts

• Download font, e.g., Hack Nerd Font and/or FiraCode Nerd Font from https://www.nerdfonts.com/font-downloads
• Unzip its archive to ~/.local/share/fonts/.
• Run fc-cache -fv

Restricted soft on ubuntu to play videos:

• sudo apt install ubuntu-restricted-extras vlc libdvd-pkg
• sudo dpkg-reconfigure libdvd-pkg

To support cut-and-paste in the micro editor:

• Use the default ("external") for the clipboard option.
• Install a proper command-line clipboard tool:
  • For Wayland: sudo apt install wl-clipboard
  • For X11: sudo apt install xclip xsel — realistically only one could be installed.
