Ubuntu中 大部分 的软件 安装/更新 都是利用 apt命令，从ubuntu的服务器 直接安装的 Ubuntu官方的服务器在国外，为了提高软件 安装/更新速度，ubuntu提供了 选择最佳服务器 的功能，可以帮助我们方便的找到一个速度最快的 镜像服务器！ 所谓 镜像服务器，就是 所有服务器的内容是相同的（镜像），但是根据所在位置不同，速度不同，通常国内服务器速度会更快一些！ 如果官方源速度还可以，就不要换了，本来就是ubuntu cn
按照以下步骤操作可以设置 ubuntu 的服务器 进入 系统设置打开 软件和更新设置 下载自… 其他站点通过 选择最佳服务器 选择速度最快的 镜像源，如下图所示：
提示：更换服务器之后，需要一个相对比较长时间的更新过程，需要耐心等待。更新完成后，再安装软件都会从新设置的服务器下载软件了 方法二方法二比方法一方便快捷哦！ #备份镜像源设置文件 sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak#编辑镜像源设置文件 sudo gedit /etc/apt/sources.list#复制下面的所有内容替换掉原文件中的所有内容(一次只可以选一个镜像源，根据你的情况选) # 阿里源 deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb 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 main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse # 清华源 deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse # 中科大源 deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-security main restricted universe multiverse deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverseubtuntu自带 #deb cdrom:[Ubuntu 20.04.3 LTS _Focal Fossa_ - Release amd64 (20210819)]/ focal main restricted # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://cn.archive.ubuntu.com/ubuntu/ focal main restricted # deb-src http://cn.archive.ubuntu.com/ubuntu/ focal main restricted ## Major bug fix updates produced after the final release of the ## distribution. deb http://cn.archive.ubuntu.com/ubuntu/ focal-updates main restricted # deb-src http://cn.archive.ubuntu.com/ubuntu/ focal-updates main restricted ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.
