Ubuntu Linux 更换源教程

因为Ubuntu自带的源已经老旧,下载速度慢,而且不稳定
本教程告诉大家如何更换Ubuntu源到国内几个比较好的源

更换源步骤如下:

  1. 备份源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
  1. 命令行打开sources.list文件
sudo gedit /etc/apt/sources.list
  1. 修改sources,list文件【本例更改为阿里镜像源】
#  阿里镜像源

deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse

deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
  1. 更新并升级
sudo apt-get update && sudo apt-get upgrade
  1. 等待更新并升级完成即可

【注意】更新过程中可能会有询问是否下载包的提示,输入y,按回车即可。

【注意!注意!注意】更新时一定要把Linux的网络连接检查是否已经连接上网络,不然会出错,我之前试一直不成功,困了好久,才发现是虚拟机的网络没有连接。。。

更新好后就可以用命令行进行安装软件或者插件了

如何用命令行安装gcc 和 g++ 参考文章:
