在Ubuntu 14.04上升级Git版本

请问有人可以告诉我这是什么问题吗？

我跑

之后$ git --version显示：

git version 1.8.2.1

看起来已经安装了git 2.x，但是我可以继续获取旧版本。

更新：

• 我已经尝试过：Git 1.7.9.5在ubuntu 12.04上升级到当前版本的GIT 2.x

• dpkg -L git参见：https : //gist.github.com/montogeek/e7bedaf03cef9a3d969b

• which git：/ usr / local / bin / git

您需要添加Git Maintenanceers存储库以获得最新的Git版本。

请按顺序运行以下命令：

sudo add-apt-repository ppa:git-core/ppa
sudo apt-get update
sudo apt-get install git

然后，检查已安装的Git的版本：

git --version

在升级现有的Git时，不一定总是需要删除它，但是如果遇到任何问题，请执行以下操作，然后重复上述步骤：

sudo apt-get remove git

您已经安装了第二个git副本，/usr/local/bin而不是系统安装的git。

不知道另一个git是如何安装的，我会说您需要从中手动删除另一个git二进制文件/usr/local/bin。
