My understanding: as of the changes made in Oracle licensing, Qt can no
longer distribute MySQL driver ready-built. You have to build it for
yourself now.
In the release distro of Ubuntu 20.04 there is a ready-built SQL driver.
If you use that then no need to build.
But if you take a later Qt you have to do the build. I don't know exactly
how this relates to your version of PyQt5 or your virtual environment
though. But I'm assuming there is a relationship?
Hope this helps, I am interested to see the correct answer.
