Hello Octus,

You are encountering an issue where a Linux OS update causes Azure Site Recovery to enter a critical state. This is mostly caused because of incompatibility between the new Linux kernel and the ASR Mobility Agent.

Can you share more specifics about the recent update and what changes were made:

What specific Linux Distribution and Version are you running currently?

What is the current version of the ASR Mobility Agent installed on the VM?

Is your Recovery Services Vault configured for Azure-to-Azure replication, or are you replicating an on-premises VM to Azure?

Verify OS version compatibility with Azure Site Recovery. Not all Linux versions are supported immediately after release.
Reinstall or update the Site Recovery Mobility Service agent on the VM after the OS upgrade.
Check for missing Python or dependency packages—some updates remove or change required components.
Review the error codes/screenshots in your PDF to pinpoint the failure stage (e.g., replication, heartbeat, etc.).
