$ nix flake update

try on your machine

The command "nix flake update" is used to update Nix flakes.

Nix flakes is a new feature in the Nix package manager that allows you to define, build, and share Nix packages and configurations in a more declarative and reproducible way. Flakes provide a structured and versioned approach to managing Nix packages and configurations.

When you run the "nix flake update" command, it fetches the latest changes from the flake sources specified in your nix flake.lock file, or directly from their remote locations if no lock file exists. It updates the local copy of the flake's sources, allowing you to ensure that you are using the most up-to-date versions of the Nix packages and configurations defined in your flake.

This command is particularly useful when working with multi-repository setups or when collaborating with others, as it ensures that you have the latest changes in all the flake sources before building or evaluating them. It helps to maintain consistency and reproducibility across different development environments or machines.
