Welcome to Nix-on-Droid!
If nothing works, open an issue at https://github.com/nix-community/nix-on-droid/issues or try the rescue shell.
-bash-5.2$ nix-shell -p cmatrix

Have you installed with flakes? If yes, you won't have a nixpkgs channel. Use `nix shell nixpkgs#cmatrix` instead.

[plchldr-jm]

yes, i've just tried flakes recently, sorry fot not pointing that one out

so, how long does it usually take to evaluating derivation 'flake:nixpkgs#cmatrix'?

[t184256]

Depends on the device performance, it's proot+storage-bottlenecked. I'd say, if it's >10 minutes worth power saving disabled and wakelock acquired from the notification, that's too much.

[plchldr-jm]

didn't see when it succeeded, so not sure how long, but it worked like a charm, thanks

    # pin the registry to avoid downloading and evaling a new nixpkgs version every time
    registry = lib.mapAttrs (_: v: {flake = v;}) inputs;

    # set the path for channels compat
    nixPath = lib.mapAttrsToList (key: _: "${key}=flake:${key}") config.nix.registry;
    

can't these lines work ????
