I had installed Nix from the Ubuntu package. I had some issues that are apparently fixed in the latest version so I uninstalled it by removing the apt package, then also following the uninstall instructions (the Ubuntu package is broken, it doesn’t remove the Nix users).
Then I installed Nix again using sh <(curl -L https://nixos.org/nix/install) --daemon. But there’s no socket to talk to it:

Any idea what could be the cause of this? I’m on Ubuntu 24.04.2 LTS
