Ubuntu – How to save a file using nano


I am trying to install Java via the terminal using the guide How to Install Oracle Java JRE on Ubuntu Linux.

Everything went perfectly fine until "Step 11: Save the /etc/profile file and exit":

Enter image description here

I spent maybe 30 minutes figuring out what ^ means (apparently Ctrl), but I cannot understand how that guy called the save command where you can choose yes and no.

I did try ^O, but I didn't get the same result as he did. How can I fix this problem?

Ctrl + X will quit the editor and you will be asked if you want to save your changes. If you do, press Y for Yes.

Ctrl + O should also work, since that means to save the file, but you won't be asked "Save modifier buffer ? " because you already told nano to save.
