Failed to start The Apache HTTP Server after installing apache2

I'm trying to install apache2 on my Ubuntu 17.10 using this command:

sudo apt-get install -y apache2

at the end of the installation it fails with:

Job for apache2.service failed because the control process exited with error code.
See "systemctl  status apache2.service" and "journalctl  -xe" for details.
invoke-rc.d: initscript apache2, action "start" failed.
