NixOS 25.05 upgrade issue: pkgs.adwaita-icon-theme

Help

I changed my nix-channel to 25.05 Stable, and I’m met with the following error when running sudo nixos-rebuild switch --upgrade to upgrade from 24.11 to 25.05:

I don’t have gnome.adwaita-icon-theme in my config file, but I’m guessing another pkg is using it?

What can I do to work around this issue?

The easiest solution is to simply add the missing theme to your config.

environment.systemPackages = with pkgs; [
  adwaita-icon-theme
];

I’ve added it into my systemPackages and the same problem still persists. Strangely, I’ve removed pkgs.aisleriot from my config file, yet it still shows up.

This was the problem. Removing nix-software-center has allowed me to move forward in the upgrade.

Glad you got that working now. You should mark your post as the solution, so if anyone stumbles over it, they’ll see that in your OP too.
