GIT: 如何正确下载远程分支到本地？
GIT: How do I properly download a remote branch to local?
想下载另一个远程分支进行维护，然后推回去。
所以我尝试了：
git switch another_branch
fatal: invalid reference: another_branch
尝试过：
git checkout --track origin/another_branch
fatal: 'origin/another_branch' is not a commit and a branch 'another_branch' cannot be created from it
尝试过：
git checkout another_branch
error: pathspec 'another_branch' did not match any file(s) known to git
尝试过：
git fetch origin another_branch:another_branch
From gitlab.my-inc.com:projname/proj
* [new branch] another_branch -> another_branch
git checkout another_branch
Switched to branch 'another_branch'
看起来不错但是:
git pull
fatal: refusing to merge unrelated histories
git branch -vv
* another_branch 421f45e normal commit comments
git branch --set-upstream-to origin/another_branch
error: the requested upstream branch 'origin/another_branch' does not exist
hint:
hint: If you are planning on basing your work on an upstream
hint: branch that already exists at the remote, you may need to
hint: run "git fetch" to retrieve it.
hint:
hint: If you are planning to push out a new local branch that
hint: will track its remote counterpart, you may want to use
hint: "git push -u" to set the upstream config as you push.
所以，我试过了：
git fetch
git fetch origin another_branch
From gitlab.my-inc.com:projname/proj
* branch another_branch -> FETCH_HEAD
仍然得到：
git branch --set-upstream-to origin/another_branch
error: the requested upstream branch 'origin/another_branch' does not exist

现在看到别人用他们的git...
玩得很好，我觉得完全不像人
所以请帮忙，提前致谢。
只要git branch -avv不列出origin/another_branch，一个简单的git switch another_branch就不行
其 guess mode 将使该命令为：
If <branch> is not found, but there does exist a tracking branch in exactly one remote (call it <remote>) with a matching name, treat as equivalent to:
$ git switch -c <branch> --track <remote>/<branch>
对于您的情况，请检查 refspec of your remote
git config remote.origin.fetch
或者，如 torek suggests in ，在 multi-values 的情况下：
git config --get-all remote.origin.fetch
应该是
fetch = +refs/heads/*:refs/remotes/origin/*
这意味着它应该获取所有个分支，而不是只获取一个分支，例如：
+refs/heads/main:refs/remotes/origin/main
如果它没有获取所有分支，请使用该 refspec (+refs/heads/*:refs/remotes/origin/*) 设置它，git fetch 将能够向您显示远程存储库的远程分支，希望包括， origin/another_branch
