`disko-install` and traditional installation both lead to an infinite blinking cursor after download and build finish

[AidanWelch]

It may be an issue in my flake so here it is:

{
  inputs.nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";
  inputs.disko.url = "github:nix-community/disko";
  inputs.disko.inputs.nixpkgs.follows = "nixpkgs";

  outputs = { self, disko, nixpkgs }: {
    nixosConfigurations.mymachine= nixpkgs.legacyPackages.x86_64-linux.nixos [
      ./configuration.nix
      disko.nixosModules.disko
      {
        disko.devices = {
          disk = {

            main = {
              device = "/dev/nvme0n1";
              type = "disk";
              content = {
                type = "gpt";
                partitions = {
                  ESP = {
                    type = "EF00";
                    size = "500M";
                    content = {
                      type = "filesystem";
                      format = "vfat";
                      mountpoint = "/boot";
                    };
                  };
                  root = {
                    size = "100%";
                    content = {
                      type = "filesystem";
                      format = "ext4";
                      mountpoint = "/";
                    };
                  };
                };
              };
            };
            
            internal = {
              device = "/dev/mmcblk1";
              type = "disk";
              content = {
                type = "gpt";
                partitions = {
                  root = {
                    end = "-1G";
                    content = {
                      type = "filesystem";
                      format = "ext4";
                      mountpoint = "/mnt/internal";
                    };
                  };
                  encryptedSwap = {
                    size = "10M";
                    content = {
                      type = "swap";
                      randomEncryption = true;
                      priority = 100;
                    };
                  };
                  plainSwap = {
                    size = "100%";
                    content = {
                      type = "swap";
                      discardPolicy = "both";
                      resumeDevice = true;
                    };
                  };
                };
              };
            };

          };
        };
      }
    ];
  };
}

And I tried

sudo nix --experimental-features "nix-command flakes" run "github:nix-community/disko#disko-install" -- --write-efi-boot-entries --flake "/mnt/sd/nixos#mymachine"

as well as

sudo nix --experimental-features "nix-command flakes" run github:nix-community/disko -- --mode disko --flake "/mnt/sd/nixos#mymachine"

both with the same result

do you have internet on the installer? usually there should be some output either way. you can try running a nix repl and do :lf /mnt/sd/nixos in there and then try to build the formatScript directly: :b nixosConfiguration.mymachine.config.system.build.diskoScript

[AidanWelch]

:lf /mnt/sd/nixos failed at first so I had to run nix flake update --experimental-features "nix-command flakes" in the dir because the repl I guess has an option passed to not update flakes. After fixing that, :b nixosConfigurations.mymachine.config.system.build.diskoScript worked, but before that I tried disko-install again, so I don't think the lack of the flake-lock was a problem. How do I now call the built format script? (Or maybe its more correct to ask how to install it)

[AidanWelch]

Actually, found it in /nix/store/[hash]-disko/bin/disko, it formatted without issue when executed so I don't know why the other attempts failed.

It may have been due to an error in my configuration.nix but that should've been reported as an error as it was when I nixos-install'd

[iFreilicht]

Just for future reference, the repl should display output something like this:

nix-repl> :b nixosConfigurations.junction.config.system.build.diskoScript

This derivation produced the following outputs:
  out -> /nix/store/446i7qiah03nxfkmbv2wr69qdfyjrbvr-disko

The out path is a link to the script.

Anyway, did you manage to fix this issue?

Sorry, I don't remember, but I assume that means I did.

[iFreilicht]

No worries, then I'll just close this issue for now. Feel free to reopen it if you find this is still a problem.

In case you're not OP and found this issue in your search for a solution, please open a new issue and link this one instead of posting a reply here :)
