This question already has an answer here:
Stuck running Ubuntu 16.04 LTS on a Lenova desktop with a small boot partition now with 0(zero) bytes after many upgrades. Currently at 4.4.0-71-generic but new upgrades fail. Have tried suggestions from many "solutions" but still can not upgrade.
None of the following free-up space:
sudo apt-get clean sudo apt autoremove --purge sudo apt-get autoremove --purge sudo purge-old-kernels sudo apt autoremove sudo apt-get purge linux-image-4.4.0-67
Have also purged all the other old linux-images that do not have dependencies.
Any new suggestions?
