我要评论ubuntu更换国内源
操作步骤
1. 对先前内容进行备份
// 备份源内容 （需要管理员权限） > sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
2. 更换国内源文
2.1 更换阿里源
// 阿里源 > echo "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" >> /etc/apt/sources.list
2.2 添加阿里公钥
// 添加公钥key > sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3b4fe6acc0b21f32
3. 更新源及软件版本
> sudo apt update -y > sudo apt upgrade -y
总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
