Just upgraded to Veeam B&R version 13.1.1.18 and I'm getting this error message when it tries to auto-update the guest components. This guest is Windows Server 2008 R2.
24/08/2026 10:37:33 am Failed REDACTED: Failed to upgrade VM components: Unable to reinstall deployer service: SSH credentials are not specified (0:00:04)
- VBR upgraded to 13.1.1.18 (Build 20260812) on 20 August.
- Server is Windows Server 2008 R2.
- Veeam Agent for Windows is 6.3.2.1205 and cannot be upgraded to 13.1 on that OS.
- Veeam Installer Service successfully upgraded to 13.1.1.18.
- Veeam Data Mover / Backup Transport remains at 13.0.1.2067.
- Components Update specifically says Veeam Data Mover service requires an update.
- The attempted update fails in ~4 seconds with:
- Unable to reinstall deployer service: SSH credentials are not specified
- This is a Windows machine and VeeamDeploySvc is the Windows Veeam Installer Service, so SSH makes no sense.
- Use persistent guest agent is disabled.
- We removed the old Veeam Guest Agent 13.0.1.2067, and the same failure remains.
