How to fix git repository broken by interrupted git fetch?

If git fetchgets interrupted for example by Ctrl-C or caused by connectivity problems, after that git fetchand also git pullfail to work.

user@computer:~/code/openttd-git$ git fetch
^C
user@computer:~/code/openttd-git$ git fetch
error: Unable to find 22d90742fc79a9011fb86ee03d8aeea66bc12657 under http://git.openttd.org/openttd/trunk.git
Cannot obtain needed object 22d90742fc79a9011fb86ee03d8aeea66bc12657
error: Fetch failed.
I believe this is not related to the repository. Using git cloneto create a copy of this broken local repository into a new local repository does not fix this. The only solution I know so far is to git clonethe entire remote repository (origin/master) into a new local repository. But is there any better (faster) solution?
我相信这与存储库无关。使用git clone将这个损坏的本地存储库的副本创建到新的本地存储库并不能解决此问题。到目前为止，我知道的唯一解决方案是git clone将整个远程存储库 ( origin/master) 放入一个新的本地存储库。但是有没有更好（更快）的解决方案？
There is Debian bug reportthat has last message from February 2011. Is this the same bug I have or is there already a fix or any solution or workaround to this? My git version is 1.7.10.
有Debian 错误报告，其中包含 2011 年 2 月的最后一条消息。这是我遇到的相同错误还是已经有修复程序或任何解决方案或变通方法？我的 git 版本是 1.7.10。

find a *.pack.tempin .git/objects/packin your local repository. Then find an .idxfile with same basename, and move both of them away (or remove them, but it is better to be safe than sorry). Rerun git fetchand it should work (well, it did for me).
在您的本地存储库中找到一个*.pack.tempin .git/objects/pack。然后找到一个.idx具有相同基本名称的文件，并将它们都移开（或删除它们，但安全总比抱歉好）。重新运行git fetch它应该可以工作（好吧，它对我有用）。
For example:
例如：
% git fetch

Try these commands:
试试这些命令：
git fsck
git gc
回答by teaforthecat
man git-fsck
says to use rsync :
说要使用 rsync ：
Any corrupt objects you will have to find in backups or other archives (i.e., you can just remove them and do an rsync with some other site in the hopes that somebody else has the object you have corrupted).
您必须在备份或其他档案中找到任何损坏的对象（即，您可以删除它们并与其他站点进行 rsync，希望其他人拥有您损坏的对象）。
rsync -av user@host:repo/.git ./.git
worked for me
对我来说有效
回答by bcmpinc
It is likely that the repository iscorrupt. Running git fsckand git gcon the server might solve it. Cloning into a separate directory and pulling from that directory will also give you the commits. Afterwards a git fetchwill work, as it only updates the refs and does not have to fetch any objects.
存储库可能已损坏。在服务器上运行git fsck和运行git gc可能会解决它。克隆到一个单独的目录并从该目录中提取也将为您提供提交。之后 agit fetch将起作用，因为它只更新 refs 而不必获取任何对象。

Are you able to run :
你能跑吗：
git reset --hard <some prior commit>
In theory, if you've just run git fetch, you should be able to:
理论上，如果您刚刚运行git fetch，您应该能够：
git reset --hard HEAD
This should discard the changes caused by the interrupted fetch operation, returning your repository to a prior state. At this point you should be able to rerun your fetchoperation.
这应该会丢弃由中断的获取操作引起的更改，将您的存储库返回到先前的状态。此时，您应该能够重新运行您的fetch操作。

Have you tried cleaning the repo?
您是否尝试过清理回购？
git gc
Be warned, as the above command also cleans the reflog stuff.
请注意，因为上述命令还会清除 reflog 内容。
