Ubuntu deals with dependency issues

When installing Git through sudo apt-get install gitthe command, you encounter a dependency problem, that is, the relevant dependencies are missing or the versions of some dependencies are too low. This can be solved in the following ways:

method one

sudo apt-get update  # 更新软件源
sudo apt-get install git

Method 2

# 使用 apt-get 命令安装软件包时，它会将下载的软件包文件存储在 /var/cache/apt/archives 目录下
sudo apt-get autoclean  # 清理 /var/cache/apt/archives 目录下那些已经过期或无效的软件包文件
sudo apt-get autoremove  # 删除不再需要的软件包及其依赖项
sudo apt-get -f install  # 修复系统中存在的软件包依赖问题
sudo apt-get install git

Method three

# 根据错误信息中提到的依赖包，手动安装
sudo apt-get install liberror-perl
sudo apt-get install git-man
......
sudo apt-get install git
