apt镜像源安装

如果 apt-get比较慢，可以替换下 apt 数据源， 更换方法:

Ubuntu采用apt作为软件安装工具，其镜像源列表记录在/etc/apt/source.list文件中。 首先将source.list复制为source.list.bak备份，然后将source.list内容改为需要的镜像源列表即可。修改完成后保存source.list文件，执行以下命令，等待更新完成即可。

安装

最新版本安装

sudo apt install golang-go 【替换掉为需要的软件】

指定版本安装

sudo apt-get install golang-go=1.15 [替换为需要的软件及版本]

APT 镜像源

选择其中一个镜像源，拷贝替换到 /etc/apt/source.list ，执行 sudo apt update
