问题

今天在一个老旧项目目录中同步代码时遇到了一个报错：unable to update local ref。

具体操作流程如下：

root@928c09c89c1c:/home/work/bag# git pull
error: cannot lock ref refs/remotes/origin/lozen/remux: refs/remotes/origin/lozen exists; cannot create refs/remotes/origin/lozen/remux
From git.baijiashilian.com:LLL/gloud/bag
 ! [new branch]      lozen/remux       -> origin/lozen/remux  (unable to update local ref)
error: cannot lock ref refs/remotes/origin/lozen/tc: refs/remotes/origin/lozen exists; cannot create refs/remotes/origin/lozen/tc
 ! [new branch]      lozen/tc          -> origin/lozen/tc  (unable to update local ref)
 * [new tag]         1.0.8.142-dasheng -> 1.0.8.142-dasheng
 * [new tag]         1.0.8.241         -> 1.0.8.241
 * [new tag]         1.0.9.021         -> 1.0.9.021

执行完 git pull 命令之后，最新的分支都已经同步下来，但是有两个分支报错了，具体的报错信息就是 unable to update local ref。其实这是一种比较常见的 Git 的报错，今天遇到了，就拿出来介绍一下解决方法。

解决

就像把大象装冰箱，总共分三步。

步骤一、清除松散对象。

命令如下：

git gc --prune=now

执行过程如下：

root@928c09c89c1c:/home/work/bag# git gc --prune=now
Enumerating objects: 3534, done.
Counting objects: 100% (3534/3534), done.
Delta compression using up to 64 threads
Compressing objects: 100% (1211/1211), done.
Writing objects: 100% (3534/3534), done.
Total 3534 (delta 2306), reused 3450 (delta 2230)

步骤二、刷新本地分支

同步远程仓库分支到本地，删除远程分支不存在但是本地还有的分支，执行过程如下：

root@928c09c89c1c:/home/work/bag# git remote prune origin
Pruning origin
URL: [e-mail]:LLL/gloud/bag.git
 * [pruned] origin/lozen

步骤三、拉取远端仓库代码

完成上面的两个步骤之后，我们就可以同步代码了，执行过程如下：

root@928c09c89c1c:/home/work/bag# git pull
remote: Enumerating objects: 123, done.
remote: Counting objects: 100% (123/123), done.
remote: Compressing objects: 100% (88/88), done.
remote: Total 123 (delta 69), reused 63 (delta 35), pack-reused 0
Receiving objects: 100% (123/123), 99.65 KiB | 2.93 MiB/s, done.
Resolving deltas: 100% (69/69), completed with 1 local object.
From git.baijiashilian.com:LLL/gloud/bag
 * [new branch]      lozen/remux -> origin/lozen/remux
 * [new branch]      lozen/tc    -> origin/lozen/tc
Already up to date.

可以看到，现在就没有问题了，已经成功把代码同步下来了，哈哈。完美！
