Programming arduino Nano from Uno

I am trying to program the nano from Uno. I have followed some guidelines on the internet but I keep getting the errors.

avrdude: Expected signature for ATmega328P is 1E 95 0F
Double check chip, or use -F to override this check.
Wrong microcontroller found. Did you select the right board from the Tools > Board menu?

Then I foind the following link which discusses rhe same issue. I changed the file .conf as given but there is no effect in the error.

show your wiring. a schema or good photo
