Updating nix channels
Published 2020-01-15, last edit 2020-05-03
I’m always forgetting this:
The command nix-channel is used to create aliases which can be referenced in configuration.nix
on nixos. The most important alias is nixos, which is used for the default pkgs reference in
your config. Channels are neat but I personally am not really a fan because it is state that exists
outside of your config. To change the default nix-channel reference:
# nix-channel --list nixos https://nixos.org/channels/nixos-19.09 # nix-channel --remove nixos uninstalling 'nixos-19.09.1861.eb65d1dae62' building '/nix/store/xsk9wjy0dpp7w7d3r3bkzxzaklqdzq6q-user-environment.drv'... created 0 symlinks in user environment # nix-channel --add 'https://nixos.org/channels/nixos-19.09' nixos # nix-channel --list nixos https://nixos.org/channels/nixos-19.09 # nix-channel --update nixos https://nixos.org/channels/nixos-19.09
And then updating the nix-channels can be done with:
# nix-channel --update
