Fix broken Nginx installation link for Ubuntu

[Copilot]

Fixes #36263

The link to Nginx installation instructions for Ubuntu was redirecting to the Nginx documentation homepage instead of the installation guide.

Changes

• Installation instructions (line 127): Updated link from broken nginx.com/resources/wiki URL to official nginx.org/en/linux_packages.html#Ubuntu
• Additional resources (line 550): Updated same broken link to point to official Nginx packages documentation
• Metadata: Added ai-usage: ai-assisted and updated ms.date to 01/07/2025

The old URL https://www.nginx.com/resources/wiki/start/topics/tutorials/install/#official-debian-ubuntu-packages has been broken since May 2024. The new URL points to the official Nginx Linux packages page maintained at nginx.org.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• nginx.org
  • Triggering command: curl -I -L REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Issue Summary

This is a valid issue. The documentation for "Host ASP.NET Core on Linux with Nginx" on Ubuntu references the link Nginx: Official Debian/Ubuntu packages, which now redirects to the Nginx documentation homepage instead of specific installation instructions. This may cause confusion or a broken workflow for users seeking to install Nginx on Ubuntu or Debian.

Scope and Article Intent

• The article targets hosting ASP.NET Core apps on Linux (specifically Ubuntu, RHEL, SUSE) with Nginx as a reverse proxy.
• It is valid for .NET Core >= 3.1 (per monikerRange line 5), and mentions using the latest stable .NET runtime (line 34).
• Visual Studio is not specifically referenced; the instructions are CLI-based, suitable for any modern .NET development environment.

Target .NET and Visual Studio Version

• .NET Core 3.1 and higher (including .NET 6, .NET 7, .NET 8, .NET 9.0).
• No specific Visual Studio version required, but compatible with VS 2019, 2022, or VS Code.

What Should Be Changed

Files and Line Numbers

• File: aspnetcore/host-and-deploy/linux-nginx.md
• Affected Areas:
  • Section: "Install Nginx" for Ubuntu (around line 124–126)
  • Section: "Additional resources" (around line 549)

Specific Lines to Update

1. Installation Instructions (Ubuntu)

• Current (line ~126):

  Use apt-get to install Nginx. The installer creates a systemd init script that runs Nginx as daemon on system startup. Follow the installation instructions for Ubuntu at Nginx: Official Debian/Ubuntu packages.

• Recommended Fix:

  • Change the link to the official Nginx Linux packages page:

    Follow the installation instructions for Ubuntu at [Nginx: Linux packages - Ubuntu](https://nginx.org/en/linux_packages.html#Ubuntu).
    

    • Optionally, summarize the official steps or link to Ubuntu's own tutorial: Ubuntu: Install and configure Nginx.

2. Additional Resources (line ~549)

• Current:

  • Nginx: Binary Releases: Official Debian/Ubuntu packages

• Recommended Fix:

  • Update the link and text:

    * [Nginx: Linux Packages (Ubuntu/Debian)](https://nginx.org/en/linux_packages.html)
    * [Ubuntu: Install and configure Nginx](https://ubuntu.com/tutorials/install-and-configure-nginx)

Looks great, approved. The link goes right to the rereqs directly.
I updated the ms.date which was showing January. I think just a typo, 1 vs 11 for Nov.
