Hi,

After this update existing `ecdsa-sha2-nistp256` keys in .ssh/known_hosts
stopped working, ssh connects fine, KIO FISH works fine, but KIO SFTP says it
can't find key for this server [1]. If I remove key using `ssh-keygen -R` KIO
SFTP adds `ssh-ed25519` key, which works fine.

But why existing ecdsa-sha2-nistp256 stopped working? Which is added by `ssh`
by default and leads to problems with KIO SFTP.

I've found old mentions of similar bug, but they are rather old, for KDE 4 SC.

[1] "The host key for this server was not found, but another type of key
exists. An attacker might change the default server key to confuse your client
into thinking the key does not exist. Please contact your system
administrator."
