Install nginx-1.20.2 on Ubuntu 20.04

I am using Ubuntu 20.04 and i have installed nginx using sudo apt update sudo apt install nginx

But after installation when i do nginx -V to check version it always shows 1.18 version instead of latest version.

How i can install latest stable version of nginx on ubuntu 20.04?

If you want to install version 1.20.2 specifically, you will need to add the official nginx repository to your Sources list.

Here is how you do it:

0. Open Terminal (or connect via SSH)
1. Ensure you have all of the prerequisites installed:

   sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring
   

2. Import the nginx signing key for apt:

   curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor \
        | sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
   

3. Create a sources .list file for apt:

   echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
        http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
        | sudo tee /etc/apt/sources.list.d/nginx.list
   

4. Pin the repository to ensure the nginx packages are installed instead of the Ubuntu-provided packages:

   echo -e "Package: *\nPin: origin nginx.org\nPin: release o=nginx\nPin-Priority: 900\n" \
        | sudo tee /etc/apt/preferences.d/99-nginx
   

5. Update apt:

   sudo apt update
   

6. Install nginx:

   sudo apt install nginx
