Then merge the files to make known_hosts contain both keys A program such as meld is a nice way to compare the two files. Then edit known_hosts to clear the original key, then ssh to the host using: ssh add the new key automatically then compare the two files. Is this possible, or is the error message just extremely misleading?ДЄ very simple way is: cp ~/.ssh/known_hosts ~/.ssh/known_hosts.bak
