Thinking of upgrading NGINX could you scan this to see if I'll shoot m,yself in the foot!

SYSTEM INFORMATION
OS type and version Debian Linux 12 >> fully up todate
Webmin version 2.621
Virtualmin version 8.0.1 Professional
Webserver version Nginx version 1.22.1
Related packages None known.

I’m thinking of following these instructions to upgrade NGINX to the latest.

Could you please have a quick scan through and check that I’m not going to “F” everything up!

Many Thanks - Nigel.

Debian
Install the prerequisites:

sudo apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring

Import an official nginx signing key so apt could verify the packages authenticity. Fetch the key:

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

Verify that the downloaded file contains the proper key:

gpg --dry-run --quiet --no-keyring --import --import-options
import-show /usr/share/keyrings/nginx-archive-keyring.gpg

The output should contain the full fingerprint 573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62 as follows:

pub rsa2048 2011-08-19 [SC] [expires: 2027-05-24]
573BFD6B3D8FBC641079A6ABABF5BD827BD9BF62
uid nginx signing key signing-key@nginx.com

Note that the output can contain other keys used to sign the packages.

To set up the apt repository for stable nginx packages, run the following command:

echo “deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg]
Index of /packages/debian/ lsb_release -cs nginx”
| sudo tee /etc/apt/sources.list.d/nginx.list

If you would like to use mainline nginx packages, run the following command instead:

echo “deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg]
Index of /packages/mainline/debian/ lsb_release -cs nginx”
| sudo tee /etc/apt/sources.list.d/nginx.list

Set up repository pinning to prefer our packages over distribution-provided ones:

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

To install nginx, run the following commands:

sudo apt update
sudo apt install nginx
