Install the prerequisites:
sudo apt install curl gnupg2 ca-certificates lsb-release
To set up the apt repository for stable nginx packages, run the following command:
echo "deb http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
| sudo tee /etc/apt/sources.list.d/nginx.list
Next, import an official nginx signing key so apt could verify the packages authenticity:
curl -fsSL https://nginx.org/keys/nginx_signing.key | sudo apt-key add -
Verify that you now have the proper key:
sudo apt-key fingerprint ABF5BD827BD9BF62
The output should contain the full fingerprint 573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62 as follows:
pub rsa2048 2011-08-19 [SC] [expires: 2024-06-14]
573B FD6B 3D8F BC64 1079 A6AB ABF5 BD82 7BD9 BF62
uid [ unknown] nginx signing key <signing-key@nginx.com>
To install nginx, run the following commands:
sudo apt update
sudo apt install nginx
