I'm trying to install ROS, and I get some missing dependencies. I tracked them down to this one which says:
it seems to me that the right package is installed but it is not recognized as such...
tesi@VisionServer:~$ sudo apt-get install python-setuptools --fix-missing
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
