Un-tarring the files works for me. But executing the command "nix-channel --update"" still does the same thing. Let me backtrack a bit for my problem. All I want to do is to install "aterm" for better display quality. And from what I read I only need to do the following steps: $ nix-channel --add http://buildfarm.st.ewi.tudelft.nl/releases/meta-environment/channels-v3/aterm-unstable $ nix-channel --update $ nix-env -i aterm I am having the same problem at the sencond step. Can I bypass it and directly go on to install step? As for whether I will be using nix regularly. Sure, if the occasion arises. I am now mostly using Cygwin setup program and directly install from the Internet. I am a light unix user and do most work on Window Desktop (firmware programming)... and that's why cygwin works so good for me.. cause I can have the bash running side by side with window application. Thanks again. CJ
