Either the packages provided by this repo are broken, you did not install all the packages needed (might be that the kernel module is in a different package, but in my opinion then there should be a dependency on it) or something went wrong during the installation
No output in the terminal window, just came back to the prompt.
Seems like I must have messed up big time somehow.
Well, yes. But it doesn't have to be your fault.
It might as well be a problem with the repo.
In fact I guess the best thing would be to:
1) Remove the repos
2) Remove all manually installed drivers, including those from the repo
3) Find a good repository on the net with a more recent driver and with sane packages (I am quite sure that an Ubuntu Forum can provide you some)
4) Install a recent driver from this repo
I am sorry that you have such a hard time installing the drivers, this should usually not be the case.
