A problem happens when just copy content in Ubuntu 镜像 to /etc/apt/sources.list for ca-certificates failure like below:
Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate. Could not handshake: Error in the certificate verification

Following Sonui's page and code in Ubuntu 镜像,a shell script is done,have fun!
At the same time,the offical page has given the same solution to fix this problem in Debian 镜像使用.
#!/bin/bash
sed -i "s@http://.*archive.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list && \
sed -i "s@http://.*security.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list && \
sed -i "s@http://ports.ubuntu.com@http://mirrors.tuna.tsinghua.edu.cn@g" /etc/apt/sources.list && \
apt update && \
apt install ca-certificates -y && \
sed -i "s/http/https/g" /etc/apt/sources.list
For python,script below will also switch to tsinghua resource:
python3 -m pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --upgrade pip
# pip3 below version 3.8 (maybe) has no config command
pip3 config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
Damn the empty-line-adding-in-the-end-of-code when switch between HTML editor and Markdown,oschina hasn't fix it!
