Git refs/remotes/origin/master does not point to a valid object
提问by Matt Harasymczuk
After the last merge to the master branch of my Git repository I have lost the ability to clone repository.
在最后一次合并到我的 Git 存储库的主分支后，我失去了克隆存储库的能力。
Cloning into test-repository...

我试过了：
cd /var/atlassian/application-data/fisheye/managed-repos/MYREPONAME.git
git gc

The following questions did not help my case:

Typically you can do:
通常你可以这样做：
git reflog master
This will give you a list of the last know positions that master has pointed to.
这将为您提供 master 指向的最后一个已知位置的列表。
Once you know this you can create a temporary branch to an older version of master ie
一旦你知道这一点，你就可以创建一个临时分支到旧版本的 master ie
git branch temp master@{1}
Then checkout temp and see if it is in proper order. If you don't see anything there then the commands that you did previously (delete the reflog, delete dangling commits, etc) have probably wiped out all ways to recovery.
然后结帐温度，看看它是否在正确的顺序。如果您在那里没有看到任何内容，那么您之前执行的命令（删除引用日志、删除悬空提交等）可能已经消除了所有恢复方法。
