Create user

The new MARBS installer no longer uses the root account for installation. One has to run it as a regular user with sudo privileges. After a fresh installation of Arch/Artix Linux, first make sure in /etc/sudoers file line: wheel ALL=(ALL:ALL) ALL (roughly at line 121) is uncommented allowing the group wheel users run sudo privileged commands. Remove the # symbol in front of it to do uncomment. Next, as root run:

useradd -m -G wheel yournewusername
passwd yournewusername
su -l yournewusername

Having done those steps, you can now run get the installer and run it with:

curl -LO marbs.kuchta.dev/marbs.sh
sh marbs.sh
