I don't use that, but to see which is the correct package name, you 
could try the command 'apt-cache policy' and see which gives some 
output, eg....
apt-cache policy oracle-vm-box
apt-cache policy oracle
apt-cache policy vm-box

Package names are one word names.

By the way, similarly you can also remove repository packages by
"sudo apt-get remove packagename" too.
