It looks like this script is provided by the package
"python-software-properties" on Ubuntu, so it should be possible to
install it with "sudo apt-get install python-software-properties".

Also, it may be worth trying one of the stock installers available from
the Racket homepage. These are just self-installing shell scripts, so it
doesn't require apt to be set up:
