Install mc (midnight commander) on Valve Steam Deck

It seems that it is not that easy to install mc on steam deck even if you ask chatgpt for help, so after some trial and error here are the steps that worked for me:

sudo steamos-readonly disable
sudo rm -rf /etc/pacman.d/gnupg
sudo pacman-key --init
sudo pacman-key --populate archlinux
sudo pacman-key --populate holo
sudo pacman -Sy archlinux-keyring
sudo pacman -S mc
sudo steamos-readonly enable

Hope this helps someone.
