Can't install home manager flake

[mags-issues]

On a fresh install, opting for using flakes, I can't seem to install home manager. I am completely new to Nix, so hope this is the right place to file this, but.. you said to open an issue if nothing works and so far.. well 😅

-bash-5.2$ nix run home-manager/master -- init --switch

Uh oh, the installation failed! Please create an issue at

    https://github.com/nix-community/home-manager/issues

if the error seems to be the fault of Home Manager.
-bash-5.2$

If your goal is to have flakes and use home-manager as a flake, then there's a template for that: https://github.com/nix-community/nix-on-droid/tree/master/templates/home-manager
