Package 'mysql-community-client-plugins' has no installation candidate

I am trying to install mysqlclient using pip and getting red text, saying there is no config.h file. I started fixing that and stucked on installing libmysqlcppconn-dev on Ubuntu 20. Terminal says

The following packages have unmet dependencies: libmysqlcppconn-dev : Depends: libmysqlcppconn8-2 (= 8.0.27-1ubuntu18.04) but it is not going to be installed

After trying sudo apt install -f libmysqlcppconn8-2 I see

The following packages have unmet dependencies: libmysqlcppconn8-2 : Depends: mysql-community-client-plugins but it is not installable

How can I fix that? Thanks everybody.
