I'm trying to install MySQL on Ubuntu 18.04. To do that, first I have donwload the package with the command:

wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.12-1_all.deb

And then, run the command:

sudo dpkg -i mysql-apt-config_0.8.12-1_all.deb

But I've got a problem with dependencies and I don't know what are these dependencies. This is part of the message that I've got:

Configurando mysql-community-server (8.0.15-1ubuntu18.04) ...

Job for mysql.service failed because the control process exited with error code.

See "systemctl status mysql.service" and "journalctl -xe" for details.

This is the log that I get consulting with "journalctl -xe":

EDIT I:

I have downloaded this package: mysql-apt-config_0.8.12-1_all.deb But checking the log, at the beginning it says to me that the process is trying to config mysql-community-server (8.0.15-1ubuntu18.04). It seems that is trying to config another packge, isn't it? Why?
