 bad object refs/remotes/origin/HEAD

How to handle git gc fatal: bad object refs/remotes/origin/HEAD error: failed to run repack
I randomly hit list today while trying to garbage collect.

$ git gc

fatal: bad object refs/remotes/origin/HEAD
error: failed to run repack

How do I deal with this?

I don't understand the ramifications分支 of this, but as suggested in this thread, when I encountered this I just did

$ mv .git/refs/remotes/origin/HEAD /tmp
(keeping it around just in case) and then

$ git gc
worked without complaining; I haven't run into any problems.

问题原因应该是，添加了新的remote，但是没有git for windows没有移除后台的origin?
