The error message tells you what the problem is:

you need to also install the following packages:


nginx-full
nginx-light
nginx-extras

[deepakdeshp]

Thank you .I had tried installing the packages listed by you but it gave error. Even purging the packages also gave error. I used
sudo apt-get install package name

sudo apt-get purge package name
and also apt-get install -f


The packages on which I ran the install and purge commands are


nginx-full
nginx-light
nginx-extras
nginx

[cariboo]

I'd suggest using:


locate nginx

to see if there are any left over files after running:


sudo apt purge <package name>

Note: you no longer need to use apt-get in version 16.04+, a simple apt works the same way, even giving you a progress bar at the bottom of the screen.

[deepakdeshp]

THank you nginx is successfully installed. Even after installation I cannnot locate nginx. That is ok


ps -e |grep ngi 8387 ? 00:00:00 nginx
8388 ? 00:00:00 nginx
root@ubuntu-i386:/home/uma# locate nginx
root@ubuntu-i386:/home/uma#




I am migrating from Apache to nginx hence was following this tutorial https://www.digitalocean.com/community/tutorials/how-to-migrate-from-an-apache-web-server-to-nginx-on-an-ubuntu-vps


I wasnt able to find any specific tutorial for Ubuntu 16 too migrate from apache to nginx.

[deepakdeshp]

I went back to earlier snapshot of the VM on which ubuntu server is running which didnt have nginx. I tried all the commands byt ran into the same error.

I tried installing nginx on a server with the lamp stack already installed, and ran into the same problem as you.

I created a new server install in a vm, without installing anything extra, I installed nginx, with zero problems and it works as it should

[deepakdeshp]

Thank you for your reply. There must be a way to install nginx along with Apache. I have seen articles using apache and nginx together. I wanted to try this too.

To install nginx make sure apache2 isn't running, but it won't do a lot of good as they won't run at the same time if they are listening on the same port. If you plan on trying the tutorial you linked to, follow it from the start, and don't skip any steps. I followed it on a vm, and after a bit of troubleshooting I got it to work. The big problem was extra directives in /etc/nginx/sites-available/default, this is a corrected version:
