Upgrade Ubuntu’s Nginx

Verify Nginx current version

$ nginx -v
# nginx version: nginx/1.18.0 (Ubuntu)

Bash

Backup your config

sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.backup

Bash

Requirements

Edit /etc/apt/sources.list and using your ubuntu release version (jammy in my case) append the next 2 lines.

deb https://nginx.org/packages/ubuntu/ jammy nginx
deb-src https://nginx.org/packages/ubuntu/ jammy nginx

Bash

Install Nginx:

sudo apt update
# This will fail and return a key id
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $key_id
sudo apt update
sudo apt install nginx

Bash
