You write that sudo and kdesudo works for you. This indicates that you are
using a distro that doesn't use a superuser (root) account, but instead
automatically gives some extended rights (membership of certain groups) to the
first added user (*Ubuntu?.
"su" is only used to change to another user and if none is specified this is
the user "root" (which has no password).
You should instead use:
sudo make aptget

Try to read up on the subject with "man su" and "man sudo".
