操作指南

using apt source with sed replacing (recomended)

# su [options] [-] [<user> [<argument>...]]
# su - $USER
o=http://security.ubuntu.com/ubuntu/
n=https://mirrors.tuna.tsinghua.edu.cn/ubuntu/
sed -i "s,$o,$n,g" /etc/apt/sources.list

o=http://archive.ubuntu.com/ubuntu/
sed -i "s,$o,$n,g" /etc/apt/sources.list

# update - update list of available packages
apt update
# upgrade - upgrade the system by installing/upgrading packages
apt upgrade

you also can use other source :

• 清华源 https://mirrors.tuna.tsinghua.edu.cn/ubuntu/
• 阿里源 http://mirrors.aliyun.com/ubuntu/
• 中科大源 https://mirrors.ustc.edu.cn/ubuntu/
• 网易源 http://mirrors.163.com/ubuntu/

or you can use replace.sh script

# only download replace.sh file
# curl -O https://ghproxy.com/https://raw.githubusercontent.com/ymc-github/use-apt-src/main/replace.sh

# get  replace.sh script usage
./replace.sh -h

# get  replace.sh script version
# ./replace.sh -v

# zero:task:s:swicth-user
# if you do not have the rights to edit file /etc/apt/sources.list
# you can swicth user with su.
# su [options] [-] [<user> [<argument>...]]
# su - $USER
# zero:task:e:swicth-user

# use some source in china
./replace.sh tsqinghua
./replace.sh aliyun
./replace.sh 163

# use offical source
./replace.sh ubuntu

# or
# curl -sfL https://ghproxy.com/https://raw.githubusercontent.com/ymc-github/use-apt-src/main/replace.sh | sh

using /etc/apt/sources.list backup files

some code snippet

# zero:task:s:add-apt-qinghua-source
sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup
file=/etc/apt/sources.list
# or use file
# file=/etc/apt/sources.list.d/qinghua_ubuntu2204.list
sudo cat <<EOF >$file

sudo apt update

you can use backup shell script :

GC_PROXY="https://ghproxy.com/"
GC_URL="https://github.com/YMC-GitHub/use-apt-src"
GC_URL="${GC_PROXY}${GC_URL}"
git clone -b main "$GC_URL"

# use-apt-src/index.sh -h

# get current using
use-apt-src/index.sh get 22.04 tsinghua
