I tried to follow the advice below and I received this...

rm: /nix: Read-only file system

To uninstall nix you will need to do the following things:

• remove the . "$HOME/.nix-profile/etc/profile.d/nix.sh" line in your ~/.profile or ~/.bash_profile
• rm -rf $HOME/{.nix-channels,.nix-defexpr,.nix-profile,.config/nixpkgs}
• sudo rm -rf /nix
  On a multi-user install, also remove all the nixbld[0-9] users

I guess there is missing a lot. what about the created volumes, launch daemon, files in /etc, ...?

Yeah, I'd like to see a supported uninstaller. I don't mind installing with a bash script if some removal steps are well defined. The whole reason people choose to use package managers like homebrew for pulling in tooling is so they have the option to clean it out if they'd like.

Can you please provide an uninstall option similar to the installer?

[benkeil]

Actually if you have installed nix and want to install it again, it will perform some uninstall steps before it install again. It should not be that complicated to write a proper uninstall script or whatever...

[sontek]

Yeah, what would be amazing. Especially for recommending it to friends and family. Feels scary to "try" nix when you can't get rid of it
