Hello Dorothy, Please ask whoever takes a look at your computer to inspect this bug. ("ubuntu bug 1693160" should suffice.) These error messages are unusual and may indicate that ssh and sshd have been set immutable, or set to mode 0000, or something even more surprising.
If you never use ssh to connect to other computers, or allow others to connect to your computer with ssh, perhaps these should be removed entirely.
