Occured here today. Running this simple command to remove old kernels and unused packages worked around the issue:
sudo apt-get autoremove --purge
Alternatively, and to be able to remove even manually installed kernels, you could use: sudo purge-old-kernels
To be able to use purge-old-kernels you may need to first install the the byobu package by running: sudo apt-get install byobu
