i want to install curses/ncurses.h file to my ubuntu.

iv gotten the file off the web using 'wget'

then untared it
then was instructed by the website to use the following commands
cd ncurses-5.5
** su root
make install

** -> this is where my problem is. i do the su root command and im promted for a password. since i am the only user & administrator on my laptop i entered my password. however it wont accept it.

any ideas what this password could be or is there any way around it.

iv tried my password, 0, root, rootroot but to no avail.
