[ALUG] kubuntu apt-get not installed

kubuntu apt-get not installed. Currently running Feisty Fawn 7.04 On booting up, my boot-up flash screen comes up. About halfway thru boot-up the flash screen chages to text (terminal or Bash Screen ?), where I can see the various aspects of the boot-up loading. It gets to a point "the program 'apt-get' is currently not installed. You can install it by typing: apt-get install apt When I type 'apt-get install apt', I get Bash: apt-get command not found, - and then the next line puts me at my root home directory with a flashing curser ready for my input. I've also tried sudo apt-get install apt and the results are the same. What I am trying to get to is my normal GUI or desktop. Your help please - elc
