"Could not resolve host: github.com" error while updating Homebrew after installing git

I'm using OS X Lion (10.7.2).

I installed Homebrew on my Mac, and I executed the command below.

$ brew install git

and then:

$ brew update
error: Could not resolve host: github.com; nodename nor servname provided, or not known while accessing https://github.com/mxcl/homebrew.git/info/refs   
fatal: HTTP request failed
Error: Failed while executing git pull  origin refs/heads/master:refs/remotes/origin/master

What happened there?

1this question belongs to [su]. check your network and that you can reach github.com with your browser – CharlesB – 2011-11-16T17:43:41.677

2what does the command ping github.com return? – Stuart Carnie – 2011-11-16T17:44:24.157

Mac OS X already has git - just install the developer tools (Xcode) if you haven't already. – Paul R – 2011-11-16T17:55:43.363

@PaulR Maybe they want a more recent version? – slhck – 2011-11-16T20:26:23.460

@slhck: could be - the question isn't very clear as to motivation – Paul R – 2011-11-17T08:00:46.013

1) If you use CLI package managers such as brew, port, fink, … some installations require root privileges. In these cases run your installation command with sudo:

sudo brew install git

2) Check wether you can github.com via a web browser.

Actually, you're not supposed to use sudo with Homebrew. Installation instructions say so, as does the FAQ.

2It's wrong to say that installation in Homebrew is "properly" done with elevated privileges. Please fix your answer. – slhck – 2011-11-16T20:25:38.313

Thanks for correcting me. I don't know brew in particular, just CLI package managers in general, and from my experience I can say that some installations require root privileges, for this cases executing via sudo can help. – porg – 2011-11-25T17:35:01.960
