Your apt/sources.list says that you are running __trusty__, not Rebecca or Cinnamon. And Trusty was never a codename for a Linux Mint release.

You should probably edit trusty in that file to the proper codename for your os. A list of valid ones can be found here: http://packages.linuxmint.com/dists/

Once you've done that, you should be able to run apt-get update, and apt-get upgrade.

Then, I wouldn't be surprised if Debian's instructions on building a new kernel package wouldn't work: https://www.debian.org/releases/stable/i386/ch08s06.html.en

thanks. I'll give that a try after I get some sleep.
