I got same issue. I have an app that vendor still using MySQL 5.6 Deprecated and it has been very difficult to install 5.6 on Debian 10 or Ubuntu 18. I made it work on Deb 9, but then php only gets to 7.0.

Worked for me on Ubuntu 20
Thank You

After installation data directory stays /usr/local/mysql/data
you can stop mysql and change location in my.cnf and copy the /usr/local/mysql/data to another location
