when I try to download something via brewing (for instance CAT) terminal says "Updating Homebrew" and it takes forever

and brew doctor says

 "Warning: Suspicious https://github.com/Homebrew/brew git origin remote found.
The current git origin is:
  https://github.com/Homebrew/homebrew-core

With a non-standard origin, Homebrew won't update properly.
You can solve this by setting the origin remote:
  git -C "/usr/local/Homebrew" remote set-url origin https://github.com/Homebrew/brew"

so I typed

git -C "/usr/local/Homebrew" remote set-url origin https://github.com/Homebrew/brew
 However, nothing happened

I am so frustrated from this. anyone can help?

Sorry for bad writing, English is not my mother-language :(

Solution

  • Run brew update with debug option: brew update -d, to see what happens, where it hangs.

    It might be caused by:

    • the slow network.
    • the waiting for the transferring of a big update.
    • the firewall issue.

    After you found the command where it hangs, try to run the exact command in the exact terminal, to debug the issue.

    If it's related to a firewall issue, you can try to use a proxy server in the command line.

    For example, you have a http proxy server available at 127.0.0.1:6152. You can set it for git:

    git config --global http.proxy http://127.0.0.1:6152
git config --global https.proxy http://127.0.0.1:6152
brew update -d

    Or set the proxy for the whole command line(only for the commands that support proxy):

    export https_proxy=http://127.0.0.1:6152
export http_proxy=http://127.0.0.1:6152
brew update -d

    To undo the above proxy config, use:

    git config --global --unset http.proxy
git config --global --unset https.proxy

    Or

    unset https_proxy http_proxy
