When trying to update I get an error message
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
But when I try to run this command the screen goes completely black and nothing happens. From what I can tell it is trying to install Linux headers when this happens. This is a fresh install of less than a week old. At this time I can not install anything new or update anything. How do I solve this issue?

I would suggest the following:
Option # 1:
Try fixing the missing packages by running the following command in the terminal:
If errors are encountered, try removing the the apt lock by running the following in the terminal:
Then:
Then run the command again:
If this does not solve the problem, please move to option # 2 below.
Option # 2:
To attempt to repair broken packages in the recovery mode, please follow these steps ( It is advised to connect your machine to Internet via Ethernet cable before you start ):
Reboot your system.
Hold the Shift key as soon as you pass the BIOS logo to enter the GRUB boot menu. You might need to repeat steps 1 and 2 a few times before you finally succeed.
Once you see the options screen, select Advanced options for Ubuntu and press Enter:
In the next screen select the second line (the on with recovery mode) and press Enter:
Wait for the initial boot process to finish and a second screen with options appears. Select Enable networking and press Enter:
If presented with a yes/no screen, choose yes and press Enter:
If all goes well, you should be now connected to the Internet. You will know if it succeeds when the options screen shows up again. Now select Repair broken packages and press Enter:
If presented with a yes/no screen, choose yes and press Enter:
When you see at the command prompt Do you want to continue? type Y and press Enter:
If all goes well, the options screen will show up again:
Reboot your machine.
