How can I restore /etc/nginx?

By mistake I have removed /etc/nginx directory in my ubuntu 11.10 PC. How can I restore the ngnix directory in /etc/nginx ?

I did these commands:

1. sudo su
2. rm -rf /etc/nginx

I want to get again /etc/nginx directory. how?

I tried this to re-install nginx:

1. sudo apt-get update
2. sudo apt-get upgrade
3. sudo apt-get install nginx

then it gives following

Reading package lists... Done

Building dependency tree   
    
Reading state information... Done
E: Unable to locate package nginx

How can i get full nginx software on ubuntu 11.10?

To recreate it, first uninstall using purge to remove even configuration files and records:

sudo apt-get purge nginx nginx-common nginx-full

then reinstall:

sudo apt-get install nginx

If above doesn't work for you, you can also try using --force-confmiss option of dpkg.

sudo dpkg --force-confmiss -i /var/cache/apt/archives/nginx-common_*.deb
