Did you check the system requirements for v12.1 - https://helpcenter.veeam.com/docs/agentforlinux/userguide/system_requirements.html?ver=60

Looks like I'm good.  Says it supports Oracle Linux Server 8.9.  

Hi, the most obvious thing to me would be checking DNS as you’ve built a new server, is the host resolving okay? If you can supply the logs from the protection group rescan please that would be useful to understand what VBR is failing on

Hi, are u test with Veeam Agent for Linux? Firstly i think u can setup in linux server. Sometimes, u cant manage from VBR server because some linux versions havent support.

Hi @TheMunkEE -

What is the specific error you’re receiving? Looks like what you posted is just some general & incomplete message. See if the logs in C:\ProgramData\Veeam\Backup provide more details.

Yes...your version of Linux is supported, but using the Agent has a LOT of pkg install pre-requisites. Did you scroll down a bit beyond the OS support to see if you have the required packages? You also need kernel-headers or kernel-devel, etc, depending on your OS.

What Protection Group is the Linux (Agent) computer in? Since you installed the Agent on the device directly, it should be in Manually Added.

So, if you still haven’t heard from Support, what I recommend:

• Check the logs in the directory above
• Provide more detail of the error if you can (blur out any sensitive info)
• Verify *all* Sys Req’s are met from the link Chris shared
• Recommend checking network connectivity & DNS as Michael shared
• Verify your Linux computer is in the proper PG

Start there and let’s see if we can assist better.

Yes but check the Kernel versions as well.  That can be an issue too.
