在 /etc/pacman.d/mirrorlist 文件的最顶端添加：
Server = https://mirrors.783578.xyz/archlinux/$repo/os/$arch
sudo pacman-key --recv-key 3056513887B78AEB --keyserver keyserver.ubuntu.com
sudo pacman-key --lsign-key 3056513887B78AEB
sudo pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-keyring.pkg.tar.zst'
sudo pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-mirrorlist.pkg.tar.zst'
sudo pacman -U 'https://mirrors.783578.xyz/chaotic-aur/chaotic-keyring.pkg.tar.zst'
sudo pacman -U 'https://mirrors.783578.xyz/chaotic-aur/chaotic-mirrorlist.pkg.tar.zst'
编辑 /etc/pacman.conf,在文件末尾追加内容
[chaotic-aur] Include = /etc/pacman.d/chaotic-mirrorlist
如果下载速度 非常快 非常慢
那就改为追加下面的内容
[chaotic-aur] Server = https://mirrors.aliyun.com/$repo/$arch
或
[chaotic-aur] Server = https://mirrors.783578.xyz/$repo/$arch
先运行
sudo apt install -y ca-certificates apt-transport-https

sudo sed -i "s|http://deb.debian.org/debian|https://mirrors.783578.xyz/debian|g" /etc/apt/sources.list
先运行
sudo apt install -y ca-certificates apt-transport-https
然后打开 /etc/apt/sources.list，将http://deb.debian.org/debian/的地址均替换为https://mirrors.783578.xyz/debian/即可。
使用sudo nano /etc/apt/sources.list打开镜像源列表文件。将类似于http://archive.ubuntu.com/ubuntu或http://cn.archive.ubuntu.com/ubuntu的地址改成https://mirrors.783578.xyz/ubuntu，之后按Ctrl-O 回车保存，按Ctrl-X退出。最后执行sudo apt update即可。
sudo sed -i 's/http:\/\/archive.ubuntu.com/https:\/\/mirrors.783578.xyz/g' /etc/apt/sources.list
sudo sed -i 's/http:\/\/cn.archive.ubuntu.com/https:\/\/mirrors.783578.xyz/g' /etc/apt/sources.list
sudo sed -i 's/http:\/\/archive.ubuntu.com/https:\/\/mirrors.783578.xyz/g' /etc/apt/sources.list.d/ubuntu.sources
sudo sed -i 's/http:\/\/cn.archive.ubuntu.com/https:\/\/mirrors.783578.xyz/g' /etc/apt/sources.list.d/ubuntu.sources
