I had ever installed MySQL in my Linux Ubuntu 18.04.6 LTS, but it had some problem, then I removed it.
However I wanted to install back again, so I followed this code to uninstall

When I try to install nginx the error comes like:

Normally I can find the answer to my problem without posting but I have looked at a few dozen posts regarding the same error message- most of them suggest installing php-mysql or php7.3-mysql or uncommenting the pdo extension in php.ini. I have tried all of these without any success. I suspect this must be some type of configuration error. The older methods of connecting to MySQL in php work just fine. The PDO driver is just not working.

There are no errors in the respectable nginx log, syslog, nor php7.3-fpm's log.

Frustrated and out of ideas, earlier today I tried upgrading to Debian bullseye assuming there may be some package incompatibility but that did not seem to help either. This took my php version to 7.4 (which seems to be working just fine everywhere else on the server)

Is there some way to find out more information as to why? Or a more detailed error log (cannot find any other than what I see in browser). I'm at a complete dead end right now.

Some info:

I am a beginner to Docker. That said, I noted the following which I think is kind of weird.

After executed a docker pull mysql/mysql-server:5.6.23 in console and after I played a little bit with Docker and his getting started tutorial, I started the pulled MySQL v5.6.23 (don't ask me why such an old version) container and I realized that the welcome message was showing the wrong version of MySQL:

I'm currently trying to setup a mysql server on my linux platform (centos). I've been following a simple Youtube tutorial here. The jist of the tutorial demonstrates how to download mySql through the following steps:

1.- Grab download link mysql via this link https://dev.mysql.com/downloads/file/?id=489467 . The direct download can be taken from here: https://dev.mysql.com/get/mysql80-community-release-el8-1.noarch.rpm

2.- Enter terminal & run wget {download link}

3.- run command rpm -qplp {filename}

4.- run command sudo rpm -ivh https://dev.mysql.com/get/mysql80-community-release-el8-1.noarch.rpm

5.- run command sudo yum install -y mysql-server

However, when I run the final command I get a bunch of "missing package" notifications. I have very little centos experience, so I'm not sure how to address this problem. The output after I run the final command is:

i'm trying to install mysql in my docker application but i'm facing with an error in my Dockerfile when running "docker-compose build".
