Boot partition full, can't remove kernels
Just before I dive into describing my issue, I just want to put out that I am quite new with Linux, so keep that in mind if I have not pointed out the obvious.
I have run into some issues with my Ubuntu server. Initially, I found that it was rebooting in a continuous loop. After forcing a power shutdown, and then removing the power cable, reconnecting and performed another boot, I was able to successfully boot the server. After some digging around, I believe the culprit to my server issues is that my boot partition is full.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-extra-3.16.0-33-generic : Depends: linux-image-3.16.0-33-generic but it is not going to be installed
linux-image-extra-3.16.0-44-generic : Depends: linux-image-3.16.0-44-generic but it is not going to be installed
linux-image-extra-3.16.0-51-generic : Depends: linux-image-3.16.0-51-generic but it is not going to be installed
linux-image-generic-lts-utopic : Depends: linux-image-3.16.0-51-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
I seem to get similar outputs when trying to remove kernels 34, 36, etc.
I've done a lot of Googling but haven't come up with a solution. There is the one report to try 'apt-get -f install' with no packages but unsure how to do that or if I should even try.
Any help or pointers on how to fix this would be most appreciated!
Thanks,

Use sudo dpkg -r <pkgname> to remove each of the older kernel packages, and then once you free up some space by doing that, sudo apt-get install -f.
