OCI: Application error: "invalid SSH version: OpenSSH version must be greater or equal to <number>"

in Linux

Applies To:

Oracle Cloud Infrastructure - Version N/A and later
Oracle Linux x86-64

Symptoms:

While executing a 3rd party application in a Oracle Linux 9 instance in OCI, the following error is seen:

err="invalid SSH version: OpenSSH version must be greater or equal to 9.2, current version: 8.7"

Cause:

The 3rd party application is not built for, or compatible with Oracle Linux 9.

Solution:

Oracle Linux 9 includes openssh version 8.7p1.

There is no more recent version of openssh that can be used in OL9, this is the only supported version.

Also, trying to install a higher version of openssh from an outside source can seriously damage the instance OS and is also unsupported by Oracle.
