Microsoft Announces Migration to Azure Linux 3.0
Heads up, Azure users! Microsoft is officially ending support for Azure Linux 0 this July 2025. If you’re still running Azure Linux 0, it’s time to plan your upgrade to Azure Linux 3.0. The clock is ticking, and staying on the old version means no more updates or security patches.
What’s New with Azure Linux 3.0?
Azure Linux 3.0 launched in August 2024 and brings a host of improvements. Expect better performance, enhanced features, and longer support—three years from its general availability date. This makes it a solid choice for modern cloud infrastructure.
Microsoft’s Azure Linux team stresses,
“To ensure continued support, security, and performance, we strongly recommend upgrading to Azure Linux 3.0 by June 2025.”This upgrade isn’t just about new features; it’s about keeping your systems secure and future-proof.
Major Updates & Important Dates
- Azure Linux 0 End of Life (EOL): July 2025
- Azure CLI 74.0: Final version supporting Azure Linux 0, releasing June 3, 2025
- Azure Linux 3.0 EOL: Summer 2027
After July 2025, Azure Linux 0 will no longer get updates or security patches. Microsoft will also stop accepting package upgrade requests for version 0. So, don’t wait until the last minute!
If you continue using Azure Linux 0, you’ll see warning messages when running Azure CLI. To silence these, set the AZURE_CLI_DISABLE_AZURELINUX2_WARNING
environment variable.
Why You Should Care
Upgrading ensures your cloud environment stays secure and performant. Microsoft warns,
“After this date, it will no longer receive updates, security patches, or support, which may put your systems at risk.”Migrating early also gives you time to troubleshoot any issues without pressure.
Plus, Azure Linux 3.0 offers a smoother experience with the latest Azure CLI versions and ongoing improvements. The Azure Linux team is ready to help with the transition, making the migration as painless as possible.
Getting Started
Start planning your migration now. Review your current Azure CLI setups and test on Azure Linux 3.0. If you hit snags, Microsoft encourages opening issues on their GitHub repo for quick support.
In summary, upgrading to Azure Linux 3.0 is essential for security, support, and performance. Don’t get caught off guard—make the move before July 2025.
