During the installation of nginx using apt repository ie when we use the following command :
apt-get install nginx we may come across some error messages like this,

Fix

Stopping the apache service (or current webserver) before we try to install nginx, would solve this issue. Once we get nginx installed, we can start apache service again.

Hence the following steps are supposed to solve this issue.

1. sudo systemctl stop apache2.service
2. sudo apt-get install nginx
3. sudo systemctl start apache2.service
