Since the 19.10 upgrade Python peewee can't talk to MySQL anymore:

raise ImproperlyConfigured('MySQL driver not installed!')
peewee.ImproperlyConfigured: MySQL driver not installed!

But all requirements are installed: peewee, mysqlclient, pysocks

Also libmysqlclient-dev, libmysqlclient21

Update:

mysql --version
mysql Ver 15.1 Distrib 10.3.17-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

Using Mariadb, which is running fine.

mariadb.service - MariaDB 10.3.17 database server
Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
Active: active (running) since 

What's the problem here?

Fixed by:

pip3 install pymysql

Apparently mysqlclient is not enough anymore.
