Faced this while running installer for setting up a 2 node RAC setup (version 19.8) on an Oracle SuperCluster. The error reported in the log is:

From the error it appears that the ssh is not setup between two nodes but actually that is not the case. Here the error message is bit misleading. It turned out to be an issue with scp with openssh version 8.x. Running the setup with -debug option gives the clue:

The reason is a new check introduced in openssh version 8.x. It is explained here, here and here. MOS note 2555697.1 also talks about it.

Workaround is to pass the -T option to scp to ignore the new checks. You can rename the scp binary to something like scp.original and create a new shell script there like this:

This time, the install should succeed. You can revert the changes back once the install is done.
