EndeavourOS is an Arch-based distro that provides an Arch experience without the hassle of installing it manually for x86_64 machines. After installation, you’re provided with a lightweight and almost bare-bones environment ready to be explored with your terminal, along with our home-built Welcome App as a powerful guide to help you along.
If you want Arch with actual training wheels you probably want Manjaro or at least a SteamOS fork like Chimera/HoloISO.
It probably would have been much smoother with an actual beginner friendly distro like Nobara and Bazzite, or possibly Mint/Pop for a more classic desktop experience.
It’s not perfect and still has woes but OP fell for Arch with a fancy graphical installer, it still comes with the expectation of the user being able to maintain an Arch install.
