hplip-3.16.8.run hangs on Ubuntu 12.04

I downloaded hplip-3.16.8 twice and ran it four different times. It always gets to a point where it is deleting the current hplip and hangs. I have also had this with other, recent hplip versions. What could be causing the hang, and how do I circumvent it so that I can use the package? Here are the last few lines on stdout:

DEPENDENCY AND CONFLICT RESOLUTION

HPLIP-3.16.8 exists, this may conflict with the new one being installed.
Do you want to ('i'= Remove and Install*, 'q'= Quit)? :i

<<HANGS>>

I just ran it again resulting in the following on stdout:
