Subject: [BUG] fetching all remote branches results in failed multiple updates
Date: Thu, 7 Mar 2019 21:44:47 +0000	[thread overview]
Message-ID: <20190307214447.GA4909@chabuduo> (raw)

Hello all,

When running the latest release of git, I receive an error when attempting to
fetch all remote branches from a repo:

    fatal: multiple updates for ref 'refs/remotes/origin/maint' not allowed

The specific ref that it fails on changes depending on the repository, but the
end result is the repo isn't cloned.

The specific configuration that causes this bug is the `remote.origin.fetch`
option, specifically:

    [remote "origin"]
    	fetch = +refs/heads/*:refs/remotes/origin/*

These settings are listed as an example in "CONFIGURED REMOTE-TRACKING
BRANCHES" of git-fetch(1), as well as expanded upon in
https://stackoverflow.com/a/40739835.

I'm running git version 2.21.0.

Full reproduction steps are below:

    [root@chabuduo ~]# useradd -m git-test -s /bin/bash
    [root@chabuduo ~]# sudo --preserve-env=SSH_AUTH_SOCK -u git-test -i
    [git-test@chabuduo ~]$ git --version
    git version 2.21.0
    [git-test@chabuduo ~]$ cat > ~/.gitconfig
    [remote "origin"]
    	fetch = +refs/heads/*:refs/remotes/origin/*
    [git-test@chabuduo ~]$ cat ~/.gitconfig
    [remote "origin"]
    	fetch = +refs/heads/*:refs/remotes/origin/*
    [git-test@chabuduo ~]$ git clone git@github.com:git/git.git
    Cloning into 'git'...
