cannot find name for group ID 30000

I am trying to infect a Debian Buster (on Contabo) but it fails

"cannot find name for group ID 30000"?

How is that such a problem?

[tcurdt]

Turns out this was some sandbox problem (that I don't understand yet).

nix build --extra-experimental-features 'nix-command flakes' --impure --expr '(import (builtins.getFlake "nixpkgs") {}).runCommand "" {} "id -g"' -L
unknown> 30000

I had to create /etc/nixos/nix.conf and add

sandbox = false
#sandbox = true
#sandbox-fallback = false

To activate I had move some dirs away and touch /etc/NIXOS.

Hey @tcurdt , I'm facing the same issue and despite creating that config and touching that file - no change here.

Any idea which files you moved?

[cawilliamson]

Another hacky workaround I managed to find was once this fails - add the following to your nix config:

services.logrotate.enable = false;

This isn't ideal but it'll get you past that error and hopefully into a working system. Then you can try to resolve the matter from there.

Sorry, cannot remember. I worked through this in the matrix chat.

I really wish this would just work :-/
It's a bit a of headache when trying to use this with cloudinit for a fresh nixos install.
