EDIT: following the instructions on this thread, I attempted to remove my old/unused kernels but could not. It looks like there's not enough space for the operation, what do I do?

However, when I run sudo apt-get purge linux-image-4.2.0-42 linux-image-4.4.0-45, I get the following messages:
gzip: stdout: No space left on device

Am I doing something wrong?

I've been getting space errors whenever I try to upgrade, and on the dist-upgrade I tried just now I got the following errors:
gzip: stdout: No space left on device

update-initramfs: failed for /boot/initrd.img-4.4.0-51-generic with 1.

and the output of uname -r:

I've tried several things based on solutions offered to some of these errors individually, but I haven't had any luck yet.
Thank you sincerely for any help!
