How to Install MySQL 5.7 on Ubuntu 22.04

MySQL 5.7 is not supported on Ubuntu 22.04, but you can download MySQL 5.7 for Ubuntu 18.04 and install it on Ubuntu 20.04 or Ubuntu 22.04

First, install libtinfo5, this is available for download from https://launchpad.net/ubuntu/bionic/amd64/libtinfo5/6.1-1ubuntu1.18.04

cd ~/
wegt http://launchpadlibrarian.net/371711898/libtinfo5_6.1-1ubuntu1.18.04_amd64.deb
dpkg -i libtinfo5_6.1-1ubuntu1.18.04_amd64.deb

The files are moved from the Offical MySQL site

So we will download it from a mirror site. If the mirror is down, you can search with the .deb file name to find another mirror.

mkdir ~/mysql57
cd ~/mysql57
