E: Package ‘git‘ has no installation candidate

1. 问题

今天在Linux上安装git如下所示:

apt-get install git -y

结果出现下列错误:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package git is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'git' has no installation candidate

2. 解决方案

针对上面错误，解决方案就是升级我们的：apt-get,使用下面命令

apt-get update
