Microsoft Linux Package Repositories

Overview

The Microsoft Linux Package Repositories are hosted on PMC (packages.microsoft.com) service. The PMC service is intended to support package hosting for customers with clients running a distribution of Linux. Microsoft builds and supports a variety of software products for Linux systems and makes them available via standard APT and YUM package repositories.

Report an issue

The package.microsoft.com team (PMC) maintains the infrastructure and metadata at packages.microsoft.com. Issues reported against this repo should involve problems downloading packages such as network connection errors, unexpected http response codes, etc. If you are having trouble installing or using a packaging due to missing dependencies, etc. we recommend contacting the team that maintains the software. Here is a list of some teams along with their issue trackers:

Configuring the repository on your Linux system

See how to host/install/upgrade Microsoft's Linux software using your distribution's standard package management tools.
In short you may enable Microsoft's Production repository for your distribution / version by installing the packages-microsoft-prod.[rpm|deb] package found at the appropriate /config/ subdirectory, and there may be additional / alternate repositories you can enable by making the .repo|.list files available to your package manager.

Microsoft's Linux Software Repository is comprised of multiple repositories:

• prod – These Production repositories (e.g. Ubuntu, Fedora, RHEL, etc.) are designated for packages intended to be used in production. These packages are commercially supported by Microsoft under the terms of the applicable support agreement or program that you have with Microsoft. The prod repositories can be located via hierarchical folder structure (e.g. https://packages.microsoft.com/fedora/36/prod/).

• insiders-fast/insiders-slow – These repositories provide a way to preview upcoming features for software released into the Production repos. Packages generally flow from insiders-fast -> insiders-slow -> prod, but note that some software in the prod repos may not use these repos, and not all versions released here will be promoted to the next stage. NOTE: Not intended for production use.

• product-specific – These repositories contain packages for specific products, for example Microsoft SQL Server on Linux. Consult the product's documentation for installation instructions, as there may be additional setup required.

Note: Packages in the Linux software repositories are subject to the license terms located in the packages. Please read the license terms prior to using the package. Your installation and use of the package constitutes your acceptance of these terms. If you do not agree with the license terms, do not use the package.

IP Addresses/Service Tags

The packages.microsoft.com infrastructure uses Azure Front Door to serve a majority of its packages. Microsoft publishes a list of Azure IP Ranges with the Front Door IPs listed under the AzureFrontDoor.Frontend service tag:

https://www.microsoft.com/en-us/download/details.aspx?id=56519

SQL packages are served from different regions so depending on your location you will receive SQL packages from an IP address in one of the following Service Tags:

• AzureCloud.eastasia
• AzureCloud.eastus2
• AzureCloud.northeurope
• AzureCloud.southeastasia
• AzureCloud.westeurope
• AzureCloud.westus2

Signature Verification

In general in rpm-based distributions it is common to sign the individual rpms but not the repository metadata, and in deb-based distributions it is common to sign the repository metadata but not the individual debs. Microsoft signs both the individual packages and the repository metadata for both types of distributions. The public keys used for verifying Microsoft signatures can be found at /keys/.

Enabling Repository Metadata Signature Checking on RPM-Based Systems

Set repo_gpgcheck=1 in your repo file.

Verify the Signature of an Individual DEB.

debsig-verify can be used to manually check the signature of an individual DEB. dpkg-sig is a competing individual-DEB signing standard with a different internal implementation, and it will not work for verifying Microsoft DEBs.

To use debsig-verify you must first create a policy file for it and provide Microsoft's public key.

1. Install debsig-verify.

   $ sudo apt install debsig-verify
   

2. Install the binary formatted (not ascii-armored) version of Microsoft's public key.

   $ wget https://packages.microsoft.com/keys/microsoft.asc -O /tmp/microsoft.asc
   $ sudo mkdir -p /usr/share/debsig/keyrings/EB3E94ADBE1229CF/
   $ sudo gpg -o /usr/share/debsig/keyrings/EB3E94ADBE1229CF/microsoft.gpg --dearmor /tmp/microsoft.asc
   

3. Create a debsig-verify policy file.

   $ sudo mkdir -p /etc/debsig/policies/EB3E94ADBE1229CF/
   $ sudo tee /etc/debsig/policies/EB3E94ADBE1229CF/microsoft.pol > /dev/null <<'EOF'
   <?xml version="1.0"?>
   <!DOCTYPE Policy SYSTEM "https://www.debian.org/debsig/1.0/policy.dtd">
   <Policy xmlns="https://www.debian.org/debsig/1.0/">
   
     <Origin Name="Microsoft" id="EB3E94ADBE1229CF" Description="[email protected]"/>
   
     <Selection>
       <Required Type="origin" File="microsoft.gpg" id="EB3E94ADBE1229CF"/>
     </Selection>
   
     <Verification MinOptional="0">
       <Required Type="origin" File="microsoft.gpg" id="EB3E94ADBE1229CF"/>
     </Verification>
   
   </Policy>
   EOF
   

4. You can now verify individual DEBs.

   $ wget https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb -O /tmp/packages-microsoft-prod.deb
   $ debsig-verify /tmp/packages-microsoft-prod.deb
   debsig: Verified package from '[email protected]' (Microsoft)
