Comment 3 for bug 1499373

I have attempted to run the command "apport-collect 1499373" as requested but the command does not run. when I press enter to run the command I receive following message: "You need to run 'sodo apt-get install python-apport' for apport-collect to work."
I have done this and then get the result:
 n-laptop:~$ apport-collect 1499373
You need to run 'sudo apt-get install python-apport' for apport-collect to work.
john@john-laptop:~$ sudo apt-get install python-apport

I have tried to run the updates but no joy . After running the command for updates I receive the following result:

After all this I am returned to the beginning with this message:
