I'm not sure I need to do anything with this now. I was upgrading with
apt-get and before it was done pressed cntrl-c before it was done. The last
thing it said was that the operation was interrupted. But when I ran the
command again the last line of the output said:

   0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

Do I need to worry about anything?
What about this file that won't upgrade?

--terminal output
