Eu já retirei o ; que tem antes do extension=pdo_mysql, porém o erro vira esse:

Olá, Aurélio! Como vai?

A mensagem de erro "could not find driver" indica que o PHP não conseguiu encontrar o driver PDO necessário para se conectar ao MySQL.

No Ubuntu, você pode instalar o driver PDO para MySQL com o seguinte comando no terminal:

sudo apt-get install php-mysql

Depois de instalar o driver, você precisará reiniciar o servidor Apache para que as alterações tenham efeito. Você pode fazer isso com o seguinte comando:

sudo service apache2 restart

E lembre-se, sempre que modificar algo relacionado ao PHP ou ao servidor Apache, é necessário reiniciar o servidor para que as alterações entrem em vigor.

Espero ter ajudado e bons estudos!

Bom dia, Aurélio! Peço desculpa pela demora em retornar.

Esse seu caso está um pouco estranho, não era para esses tipos de erros estarem acontecendo, mas tudo bem, vamos tentar resolver isso!

Precisarei de mais informações para poder ajudá-lo, então peço que compartilhe comigo todos os passos e comandos que você realizou para a instalação do PHP e como exatamente você está testando para que esse erro seja apresentado.

Bom dia, eu desinstalei tudo e instalei novamente, sanando assim o erro. Grato
