"brew update" command fails

Hi,

We are using CircleCi to build several iOS projects.

We’ve added the - brew update command in our circle.yml to ensure the last version of Homebrew is installed.

It was previously working, but now our builds are always failing with the following error:

$brew update
/usr/local/Library/brew.sh: line 32: /usr/local/Library/ENV/scm/git: No such file or directory
/usr/local/Library/brew.sh: line 32: /usr/local/Library/ENV/scm/git: No such file or directory

Error: update-report should not be called directly!

brew update returned exit code 1

Action failed: brew update

Was there any recent changes to containers that prevent to update Homebrew?

(Hacky solution at the bottom)

It seems that Homebrew isn’t able to detect the git client to use during the dependency cycle. The output from brew config reports this:

HOMEBREW_VERSION: 0.9.9

This should have an entry like:

Git: 2.8.2 => /usr/local/bin/git

Through trial and error, it seems that calling brew update twice resolves the issue temporarily. Our dependencies section now looks like:

dependencies:
  pre:
    - (brew update || brew update)
    - (brew upgrade xctool || true)

This is a hacky solution, but at least it gets our builds working again for now.

Thanks David, we’ll use this quick fix for now.

This is a confirmed issue with Homebrew, per them it should be fixed, but if not the following will correct.

cd "$(brew --repository)" && git fetch && git reset --hard origin/master

Check this also works
run:
brew upgrade
before
brew update
Like in this SOF question

April 2017, still having this issue. Running brew update twice works for me as well.
