I am unable to upgrade to 1.6 on one of my machines for an unknown reason. I updated my machine by doing 'nixos-rebuild --upgrade switch' and rebooting.
$ nixos-version 13.09pre5022_71365b7-38d54cf (Aardvark) $ nix-env --version nix-env (Nix) 1.5.3 $ which nix-env /run/current-system/sw/bin/nix-env $ sudo nix-channel --list nixos http://nixos.org/releases/nixos/channels/nixos-unstable $ nix-env -qa '*' | grep -e '^nix' nix-1.5.3 nix-1.6pre3215_2c1ecf8 nix-generate-from-cpan-1 nixops-1.0.1 nixpkgs-lint-1 Interesting fact: on my other machine that did upgrade properly, the output of the grep is different: $ nix-env -qa '*' | grep -e '^nix' nix-1.5.2 nix-1.5.3pre3141_1b6ee8f nix-generate-from-cpan-1 $ nix-env --version nix-env (Nix) 1.6pre3215_2c1ecf8 Any suggestions?
