Why won't apache start?

Question

Apache HTTP Server

My computer refuses to start working, as it stopped on New Year's Eve, and does not leave the holiday mode.

sudo service apache2 start
Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.

In journalctl -xe, to be honest, I can’t understand anything.

I usually solve problems always ends with a reinstallation, either Apache or mint in general.
But now I'm trying to figure out what the problem is)))

Answer 1

Try like this
and like this
And is it really the reason in Apache, judging by the logs, you have some kind of network problem, mb configuration has gone off or something like that .. Does the rest work fine?
