使用git 1.6.4.2时，当我尝试git pull时，会出现以下错误：
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)
我尝试过git远程梅干起源，但没用。
当前回答
解释：您的远程repo（在GitHub/BitBucket中）分支似乎已被删除，尽管您的本地引用未被更新并指向不存在的引用。
为了解决这个问题：
git fetch --prune
git fetch --all
git pull
额外阅读-参考Git文档：
gitfetch-从另一个存储库下载对象和引用--全部取下所有遥控器。--修剪提取后，删除远程上不再存在的任何远程跟踪分支。
其他回答
尝试使用以下方法清理本地存储库：
$ git gc --prune=now
$ git remote prune origin
man git gc（1）：
git-gc - Cleanup unnecessary files and optimize the local repository
git gc [--aggressive] [--auto] [--quiet] [--prune=<date> | --no-prune]
Runs a number of housekeeping tasks within the current repository, such as compressing file revisions
(to reduce disk space and increase performance) and removing unreachable objects which may have been
created from prior invocations of git add.
Users are encouraged to run this task on a regular basis within each repository to maintain good disk
space utilization and good operating performance.
man git远程（1）：
git-remote - manage set of tracked repositories
git remote prune [-n | --dry-run] <name>
Deletes all stale remote-tracking branches under <name>. These stale branches have already been
removed from the remote repository referenced by <name>, but are still locally available in
"remotes/<name>".
git fetch--prune为我修复了这个错误：
[marc.zych@marc-desktop] - [~/code/driving] - [Wed May 10, 02:58:25]
[I]> git fetch
error: cannot lock ref 'refs/remotes/origin/user/janek/integration/20170505': 'refs/remotes/origin/user/janek/integration' exists; cannot create 'refs/remotes/origin/user/janek/integration/20170505'
From github.com:zooxco/driving
! [new branch] user/janek/integration/20170505 -> origin/user/janek/integration/20170505 (unable to update local ref)
From github.com:zooxco/driving
[marc.zych@marc-desktop] - [~/code/driving] - [Wed May 10, 02:58:30]
[I]> git fetch --prune
- [deleted] (none) -> origin/user/janek/integration
不过，这假设有问题的分支已在远程删除。
您也可以将其添加到~/.gitconfig中，以在运行git fetch时自动修剪：
[fetch]
prune = true
这对我来说很有用：
git gc --prune=now
对我来说，我是这样解决的：
rm .git/refs/remotes/origin/master
git fetch
之后，我从github收到了这条消息。
没有当前分支的跟踪信息
所以接下来我做的是：
git branch --set-upstream-to=origin/master master
git pull
尝试了这些，但没有对我起作用：
$ git gc --prune=now
$ git remote prune origin
$ git fetch --prune
我不得不通过删除本地文件夹并再次克隆来解决这个问题。
