使用git 1.6.4.2,当我这样做时,git pull我收到此错误:

error: unable to resolve reference refs/remotes/origin/LT558-optimize-sql: No such file or directory
From git+ssh://remoteserver/~/misk5
 ! [new branch]      LT558-optimize-sql -> origin/LT558-optimize-sql  (unable to update local ref)
error: unable to resolve reference refs/remotes/origin/split-css: No such file or directory
 ! [new branch]      split-css  -> origin/split-css  (unable to update local ref)

我试过git remote prune origin,但没有用.

这是错误消息:

 error: cannot lock ref 'refs/remotes/origin/master': unable to resolve reference 'refs/remotes/origin/master': reference broken
    From https://bitbucket.org/abc/abc
     ! [new branch]        master     -> origin/master  (unable to update local ref)

当我试图拉,然后它显示"完成有错误,见上文",我忘了我之前做了什么,所以它导致这个错误出现后我拉请求.我该怎么办 ？
