Upgrade failed with "protobuf requires Python '>=3.7'.."

My server use the version 2.3 Build 4
image

When I start the update script it runs for a while, but then I get this error message.

Any ideas?

For your information, I am still using CentOS 7, but unfortunately the support has recently expired and CentOS 7 can no longer be updated.

This is what it shows me when I search for updates for the CentOS 7 server.
