The debug log on the client

Nmap scan of the server
I assume this is a client misconfiguration and duplicate of a bug #2088750. I think you have somwhere in the client configuration written HostkeyAlgorithms ssh-rsa, which is no longer supported in RHEL9. Yes it was and missing cipher, but the error message is strange. Better will be an message like "Cipher error: requested foo available bar". Because the error only happens after enter the correct password. When using an wrong one, the error will not happens. I agree that the error message is weird. Hopefully we will improve the diagnostics, but I close the bug as a duplicate. *** This bug has been marked as a duplicate of bug 2088750 *** |
