更新Ubuntu软件源

大家好，欢迎再次相聚，我是你们的朋友全栈君。

Ubuntu软件源的原始配置文件路径是/etc/apt/sources.list，其内容如下：

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to# newer versions of the distribution.deb http://archive.ubuntu.com/ubuntu/ focal main restricted# deb-src http://archive.ubuntu.com/ubuntu/ focal main restricted## Major bug fix updates produced after the final release of the## distribution.deb http://archive.ubuntu.com/ubuntu/ focal-updates main restricted# deb-src http://archive.ubuntu.com/ubuntu/ focal-updates main restricted## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu## team.

要备份原有的软件源，可以使用以下命令：

cp /etc/apt/sources.list /etc/apt/sources.list.bak

接下来，您需要修改sources.list文件的内容。可以使用以下指令进行编辑：

vi /etc/apt/sources.list

将sources.list的内容修改为以下内容：

# 清华源deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricteddeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricteddeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial universedeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates universedeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial multiversedeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates multiversedeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiversedeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricteddeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security universedeb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security multiverse# 阿里源deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

修改后的sources.list内容如下：

完成Ubuntu软件源的更换操作。如果您在Docker中更换源（不使用vim），可以使用以下命令：

echo "">/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial main restricted">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates main restricted">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial universe">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates universe">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial multiverse">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-updates multiverse">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security main restricted">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security universe">>/etc/apt/sources.listecho "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu/ xenial-security multiverse">>/etc/apt/sources.listecho "deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse">>/etc/apt/sources.listecho "deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse">>/etc/apt/sources.listecho "deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse">>/etc/apt/sources.listecho "deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse">>/etc/apt/sources.listecho "deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse">>/etc/apt/sources.listecho "deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse">>/etc/apt/sources.listecho "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse">>/etc/apt/sources.listecho "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse">>/etc/apt/sources.listecho "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse">>/etc/apt/sources.listecho "deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse">>/etc/apt/sources.list
