ubuntu更换APT源

2022-03-02   


文件位置:/etc/apt/sources.list
在修改前建议先备份一下文件

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bakup

使用vim编辑sources文件

sudo vim /etc/apt/sources.list

在每行的开头添加“#”注释掉内容,也可以直接全部删除,将新的源连接地址复制进去。

刷新源:sudo apt update
更新所有已安装软件:sudo apt upgrade

使用 “apt install 包名” 可以进行单个软件包的更新
