首先查看原地址


sudo vim /etc/apt/sources.list

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://archive.ubuntu.com/ubuntu/ bionic main restricted
# deb-src http://archive.ubuntu.com/ubuntu/ bionic main restricted

## Major bug fix updates produced after the final release of the
## distribution.
deb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted
# deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted

## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu
## team. Also, please note that software in universe WILL NOT receive any
## review or updates from the Ubuntu security team.
deb http://archive.ubuntu.com/ubuntu/ bionic universe
# deb-src http://archive.ubuntu.com/ubuntu/ bionic universe
deb http://archive.ubuntu.com/ubuntu/ bionic-updates universe
# deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates universe

备份原来的源以防还用的上

sudo cp /etc/apt/sources.list /etc/apt/sources.list.20210808

vim打开

sudo vim /etc/apt/sources.list

执行替换

%s/security.ubuntu/mirrors.aliyun/g
%s/archive.ubuntu/mirrors.aliyun/g

wq保存再执行apt-get update就快多了而且地址也换成阿里云了
