      This error typically indicates that MariaDB Connector/C, a dependency which must be preinstalled,
      is not found.
      If MariaDB Connector/C is not installed, see installation instructions
      at: https://github.com/mariadb-corporation/mariadb-connector-c/wiki/install.md.
      If MariaDB Connector/C is installed, either set the environment variable MARIADB_CONFIG or edit
      the configuration file 'site.cfg' to set the 'mariadb_config' option to the file location of the
      mariadb_config utility.

I found many subject and answer about this topic like update and upgrade the system, upgrade my pip version or install packages like libmariadbclient-dev, setuptools or libmysqlclient-dev.

I installed libmariadb-dev on my system too but none of these solutions works for me.

python3 --version : Python 3.8.10

pip --version : pip 22.1.2

Thanks for your help !

It is not enough to install libmariadb-dev, you also need to install libmariadb (afaik it is libmariadb3 on focal), since mariadb-config binary is not part of the dev package.

sudo apt-get install libmariadb3 libmariadb-dev.

Another option would be to install the server package, which also contains MariaDB Connector/C.
