Apologies, I am aware this is a common question, but I have tried numerous things and still can't get my system to update due to 100% usage of boot disk.

I have no idea what to do.

uname -r = 3.16.0-62-generic

$ df -h

/dev/sda1                    511M  3.4M  508M   1% /boot/efi

If I try sudo apt-get autoremove, I see:

  • try sudo apt-get clean then sudo apt-get update anf finally sudo apt-get install -f – Pascal Fares Mar 24 '16 at 9:08
  • The outcome is the same. – taffer Mar 24 '16 at 9:09
  • Would you please add the output of the command "df -h"? – EnzoR Mar 24 '16 at 9:15
  • i think the reason is /dev/sda2 237M 225M 0 100% /boot (the /boot i full) if you havemany kernel try to clean old ones before – Pascal Fares Mar 24 '16 at 9:25
  • Provide the output of "ls -l /boot". The only easy option here is to thin it out by removing older and possibly not needed kernel images. 225 MB should be more then enough for a kernel or two. It looks like there are quire more. Without some repartitioning, you'll need to keep an eye on the content of that fs. – EnzoR Mar 24 '16 at 9:28

It's probably because too many kernels are installed on your system.

So, you have to remove the old kernel images via dpkg.

  1. Detect no longer required kernels:

    dpkg -l 'linux-[ihs]*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\([-0-9]*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d'

  2. After the check if the correct kernel versions were detected, you can remove them:

    dpkg -l 'linux-[ihs]*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\([-0-9]*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo dpkg -P

  3. Afterwards you should check if corrupt or incomplete packages exist:

    dpkg -l linux-[ihs]* | sed '1,6d'| grep -vE '^ii|^un|^rc'

  4. In case the stdout is not empty you should install the corrupt/incomplete packages:

    sudo apt-get -f install

(The commands are from the German Wiki Ubuntuusers.de. I used them in the past too and they worked fine for me.)
