When I connect to my "OpenSSH_8.2p1 Ubuntu-4ubuntu0.4" server alternating using "`sftp -v -o HostKeyAlgorithms=ecdsa-sha2-nistp256 test-user@localhost`" and "`sftp -v -o HostKeyAlgorithms=rsa-sha2-256 test-user@localhost`" I always get when switching from one algorithm to the other the following warning: "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!". Is this the correct behavior that it is not possible to use ECDSA and RSA Host-Key-Algorithms in parallel or is this a bug?
