Update attempt delivers message 'Not enough free disk space' with the recommendation to free up space on /boot. I have tried all the clean up techniques I know, but essentially it is filled with all necessary stuff. What I can't understand is why the /boot volume is limited to only 40mb when there is 800gb free on my hard drive? What should I do about this? Thanks!
I have only Ubuntu installed, but the machine came with Win 8.
Note: This solution involves moving /boot into to the linux root drive (/). It also involve grub-update, hence it is recommended to have a live CD/USB with you.
This is one way to forget about this issue, as all the contents will be moved to the root drive, which will have a much larger size.
Create a new copy of all the contents in /boot with the same permissions
$ cp -pr /boot /boottemp
Unmount the /boot partition
$ umount /boot
Comment (add a # in the beginning) the entry corresponding to the /boot partition in file /etc/fstab
$ rmdir /boot
Make the /boottemp folder the new boot folder
$ mv /boottemp /boot
Run grub update
$ sudo update-grub
$ sudo reboot
