description	Update per-distro package files in release-notes/<version>/distros/ documenting dependencies and .NET package availability for each Linux distribution.

Update Distro Packages

Maintain per-distro package files under release-notes/<version>/distros/ in the dotnet/core repo. These files document what packages each Linux distribution needs to run .NET and which .NET packages are available in each distro's archive.

When to use

• A new .NET version is being set up (seed from previous version)
• A new distro release ships (e.g. Ubuntu 28.04) and needs adding
• Periodic audit of .NET package availability across distros
• Dependencies may have changed between .NET versions

File layout

release-notes/11.0/distros/
  index.json            # plain index listing all distro files
  dependencies.json     # hand-maintained, distro-agnostic package list
  ubuntu.json           # per-distro: dependencies + dotnet packages
  debian.json
  alpine.json
  ...

Prerequisites

The release-notes tool must be installed globally. It provides the pkgs.org query client:

release-notes query distro-packages --dotnet-version 11.0

Requires PKGS_ORG_TOKEN environment variable (pkgs.org Gold+ subscription).

Inputs

The user provides:

• dotnet/core path — local path to the dotnet/core repo (e.g. ~/git/core)
• .NET version — which version to work on (e.g. "11.0")
• Optionally, specific distros or tasks to focus on

Process

1. New .NET version setup

When setting up distros/ for a new version (e.g. 12.0):

1. Read the previous version's distros/dependencies.json
2. Ask the user whether the dependency list has changed for the new version (new dependencies, removed dependencies, changed minimum versions)
3. Create dependencies.json for the new version, updating as needed
4. Copy per-distro files from the previous version as a starting point
5. Update distros/index.json to list all files
6. The dependency mappings (e.g. Ubuntu 24.04 uses libicu74 for libicu) carry forward unchanged

2. Adding a new distro release

When a new distro release ships (e.g. Ubuntu 28.04):

1. Read the existing distro file (e.g. ubuntu.json)
2. Query pkgs.org for the new release's dependency package names:
   • Look up each package ID from dependencies.json (libc, openssl, libicu, etc.)
   • Find the concrete package name in the new release
3. Add the new release entry with its dependencies
4. Query for .NET package availability in the new release
5. Keep releases ordered by version (newest first in the file)

3. Updating .NET package availability

1. Run release-notes query distro-packages --dotnet-version <ver> to get current package data from pkgs.org
2. For each distro file, update dotnet_packages (built-in feed) and dotnet_packages_other (alternative feeds)
3. Update the root dotnet_versions array to reflect all available versions
4. Dictionary keys: versions descending, feed names ascending, component names ascending

4. Verify and commit

1. Validate JSON files parse correctly
2. Ensure index.json lists all distro files
3. Show the user a summary of changes
4. On confirmation, commit

Schema reference

dependencies.json (hand-maintained)

{
  "channel_version": "11.0",
  "packages": [
    {
      "id": "openssl",
      "name": "OpenSSL",
      "required_scenarios": ["cryptography", "https"],
      "min_version": "1.1.1",
      "references": ["https://www.openssl.org/"]
    }
  ]
}

Per-distro file (e.g. ubuntu.json)

{
  "name": "Ubuntu",
  "dotnet_versions": ["10.0", "9.0"],
  "install_command": "apt-get install -y {packages}",
  "releases": [
    {
      "name": "Ubuntu 24.04 (Noble Numbat)",
      "release": "24.04",
      "dependencies": [
        { "id": "libc", "name": "libc6" },
        { "id": "openssl", "name": "libssl3t64" }
      ],
      "dotnet_packages": {
        "9.0": 
               
               
        
      
       
         
           
           
             
                   
            
          
        
      
    
  

index.json

  "channel_version": "11.0",
  "distros": ["alpine.json", "debian.json", "ubuntu.json"]
}

Naming and ordering conventions

• File names use snake_case (e.g. azure_linux.json, centos_stream.json, opensuse_leap.json)
• JSON property names use snake_case (handled by serializer)
• Alpha ascending for names/strings (dependency IDs, component names, feed names)
• Descending for numbers/versions (newest first)

Key facts

• dependencies.json is hand-maintained, not generated. It rarely changes between .NET versions.
• Per-distro files are the durable source of truth. For new .NET versions, seed from the previous version.
• Microsoft is phasing out packages.microsoft.com for Ubuntu 24.04+ and newer Fedora
• Alpine uses different naming: dotnet{major}-{component} (e.g. dotnet9-sdk)
• Alpine packages are in the community repo, not main
• Use pkgs.org to look up concrete package names for new distro releases
• The dotnet/docs repo has authoritative availability tables in docs/core/install/linux-*.md
