当前回答
我尝试了多种选择，但没有一个对我有效。下面的命令对我很有用。把它放在这里，如果它能帮助人们，以防其他选择不起作用。
Git拉-p
-p --prune Before fetching, remove any remote-tracking references that no longer exist on the remote. Tags are not subject to pruning if they are fetched only because of the default tag auto-following or due to a --tags option. However, if tags are fetched due to an explicit refspec (either on the command line or in the remote configuration, for example if the remote was cloned with the --mirror option), then they are also subject to pruning. Supplying --prune-tags is a shorthand for providing the tag refspec.

清晰的步骤
在终端 cd / . / /遥控器/参考文献来源 做ls，你会看到一些树枝和头部 移除你认为有问题的分支 rm branchname 如果它不起作用，删除所有分支/HEAD 你可能想拉一把
希望它现在有用。
同样的情况在这里，但没有关于张贴的评论在我的情况下是正确的，我只有一个分支(master)，只使用Unix文件系统，这个错误随机发生时，我运行git fetch -progress -修剪起源和分支是前方或'origin/master'。没有人可以提交，只有1个用户可以推送。
注意:我在acme存储库中有一个子模块，acme有新的子模块更改(新提交)，我需要先用git子模块更新做一个子模块更新。

要解决这个问题(在我的例子中)，如果你的分支在原点之前，只需运行第一个git push。
永久解决
Git update-ref -d解决了这个错误的实例，例如:
git update-ref -d refs/remotes/origin/user
注意，这不会影响远程。
在我的例子中，后续的git获取再次获取该分支，并且后续的git获取/拉不再给出错误“remote ref is at but expected”。
如果这不起作用，临时修复:
还要注意的是，如果你不关心所讨论的分支(例如，你只想更新master，而不是origin/user)，一个git pull的变通方法是获取然后合并你所关心的特定分支，例如。
git fetch # may give an error for a particular branch, but other branches will still be successfully fetched
git merge origin/master
我必须从命令行中删除我的分支:
.git\refs\remotes\{my remote}\{**my branch**}
然后手动操作:
git pull [remote_name] [branch_name]
我找到了改动的地方。
注意:我正在使用SourceTree，无法进行拉取。
