Help with resolving lingering xz-5.6.0 & xz-5.6.1

Help
1

When searching for xz versions 5.6.0 & 5.6.1 I still find the packages in my nix store after running sudo nix-store --optimise -v -j auto, sudo nix-collect-garbage -d and sudo nixos-rebuild switch.

My current xz version is 5.4.6. I haven’t enabled open ssh and sshd doesn’t seem to be running.

How can I delete the packages or do I still need them as they are live?

xz --version

Hello,

You probably have a bunch of gc roots/old generations still using it or that have not been garbage collected yet. See Storage optimization - NixOS Wiki for more info

Thank you.

Running the garbage collection without sudo worked to resolve the issue.
