重命名分支后无法打开FETCH_HEAD [英] Cannot open FETCH_HEAD after renaming a branch

问题描述

我得到错误：

  error：can not open .git / FETCH_HEAD：Permission denied 
  

当我打开这个文件时，我发现被引用的分支仍然被设置为分支'master'。 p>

看看远程存储库，我看到名为'master'的分支依然存在，除了重新命名的分支，我合并了最后的更改。我认为在某处出现了问题，重命名在远程存储库中未正确复制。

我试图手动编辑 FETCH_HEAD （改变完整的SHA和尖锐的分支），但是我仍然得到这个错误。当然，由于名为'master'的分支总是存在，所以我不能再重新命名。

有没有办法解决这个问题？

1. 我已经重新命名了一个分支（但这似乎不是主要的原因）
   
2. 我也更新了用户名和电子邮件地址（这可以支持我作为其他用户执行过各种操作的分析）


3. 由于 SourceTree的已知bug（它突然停止了某些远程分支的跟踪）

因为使用 chown 命令似乎并不有效，所以我最终使用以下过程解决了我的问题： p>

1. 使用命令 rm -f .git / FETCH_HEAD 删除被拒绝的文件（如这个答案）


2. 使用命令 git branch -u重新连接未跟踪分支（如此评论）

之后，能够获取所有远程分支，现在，所有远程分支都与我的本地存储库正确同步。

After having renaming the 'master' branch (using Sourcetree), I can't fetch anymore the changes done in the remote repository.

I get the error:

error: cannot open .git/FETCH_HEAD: Permission denied

When I open this file, I see that the referenced branch is still set toward branch 'master'.

Taking a look at the remote repository, I saw that a branch with named 'master' still exists, in addition to the renamed branch where I merged my last changes. I think there have got a problem somewhere and the renaming was not replicated correctly in the remote repository.

I have tried to manually edit the FETCH_HEAD (changing the full SHA and the pointed branch), but I still get this error. Of course, I can not rename again as before my main branch, since a branch named 'master' is always present.

Is there a way around this problem?

解决方案

In fact, it seems that this problem is (potentially) due to the combination of various factors:

1. I have actually renamed a branch (but that doesn't seem to be the major causek)
2. I have also updated username and email address (this can support the analysis that I have performed various operations as some other user)
3. Some branches was unable to be fetched certainly because of a known bug of SourceTree (which have suddenly stopped tracking of some remote branches)

As using chown command doesn't seem to be effective, I have finally resolved my issue using the following process:

1. Removing the denied file using the command rm -f .git/FETCH_HEAD (as described in this answer)
2. Reconnecting the untracked branches using the command git branch -u (as described in this comment)

After that, I was able to fetch all the remote branches, and now, all is correctly synchronized with my local repository.
