I am unable to install or update any software on my machine.

Using my incredible powers of inference I deduced that /boot was full and was causing all my heartache.

notlinus@NS0:/boot$ df -h

Im sure this must be a duplicate question but after searching around the solutions to similar questions did not aleviate my predicament.

Lastly, I am a RHEL admin so please excuse my apt ignorance - our BIND servers have to be on Ubuntu as a condition of some free colo space by our sister company. What am I doing wrong that caused this issue and how can I avoid it happening in future?

When I try similar solutions on this site such as How do I free up more space in /boot? I get:

notlinus@NS0:/boot$ sudo dpkg -fl linux-{image,headers}-"[0-9]*" | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e '[0-9]' | xargs sudo apt-get -y purge

    Possible duplicate of Can't clean a full /boot because of unmet dependencies. I'd also recommend upgrading, as Vivid is no longer supported. – mikewhatever Mar 4 '16 at 11:24

  • This answer provides a way of removing packages with unmet dependencies, if nothing else works. Namely, you need to use sudo dpkg --force-all -P pkgname. Script it if you want to, but it looks like that's the way to go. – mikewhatever Mar 4 '16 at 12:51

Thanks @mikewhatever,

sudo dpkg --force-all -P pkgname was the answer

So: sudo dpkg --force-all -P linux-image-extra-3.19.0-26-generic did it for me

  • borrowing from another answer, the command echo $(dpkg --list | grep linux-image | awk '{ print $2 }' | sort -V | sed -n '/'$(uname -r)'/q;p') $(dpkg --list | grep linux-headers | awk '{ print $2 }' | sort -V | sed -n '/'"$(uname -r | sed "s/\([0-9.-]*\)-\([^0-9]\+\)/\1/")"'/q;p') | xargs sudo dpkg --force-all -P worked beautifully for me to pass all but the active kernel for removal. – b_laoshi Oct 8 '19 at 7:55

The problem is because you ran out of space on the /boot partition.

Easily create some free space via sudo truncate -s 0 /boot/initrd.img-oldest-version

NOTE: do not truncate the highest 2 initrd versions!

After this sudo apt autoremove -f will succeed but it will take nearly forever to complete because it will rebuild initrd for all images and reinstall grub twice every time it removes one old kernel image. With 20 old kernel images it will rebuild the initrds nearly 400 times!

You can work around that ridiculous rebuilding by disabling the initrd generation tool:

sudo mv /etc/kernel/postinst.d/initramfs-tools /etc/kernel/postinst.d/initramfs-tools.real
sudo ln -s /bin/true /etc/kernel/postinst.d/initramfs-tools

Then issue sudo apt autoremove -f and when you're done...

sudo rm /etc/kernel/postinst.d/initramfs-tools
sudo mv /etc/kernel/postinst.d/initramfs-tools.real /etc/kernel/postinst.d/initramfs-tools
sudo /etc/kernel/postinst.d/initramfs-tools $( uname -r )

NOTE: If the running kernel isn't in /boot any more then you may need to supply the kernel version manually in place of uname -r

After you're done, consider manually installing a specific kernel such as the current one, and then enabling apt-autoremove. This will ensure you always have the chosen image to boot from, plus whatever the latest is.

  • Why not sudo rm -f /boot/*3.19.0-25.26* and get more than one file (initrd.img-3.19.0-26-generic) at once? – WinEunuuchs2Unix May 16 '19 at 1:53

If your issue is because of lack of space, then you might have a way out. If you look closely, then you can see:

 Filesystem                Size  Used Avail Use% Mounted on
 /dev/sda1                 236M  234M     0 100% /boot

You will see that the size of the partition is 236M, while used is 234M. System has reserved 2 MB for such emergencies. Free it up for your use by issuing the command:

 sudo tune2fs -m 0 /dev/sda1

You will have 2M of free space which might help you out of your situation.

Another way out will be to abandon that partition as boot entirely and use change the fstab (remove /boot ) and create a /boot on the root partition.

Copy everything over from the (now) old boot to new boot and then complete the commands.

Since Ubuntu 14.04 Trusty , this command supports older kernels except the last two . It is very easy and safe to remove old kernels other than the last 2 by typing in a terminal the command:

sudo apt-get autoremove --purge
  • sudo apt-get autoremove --purge The following packages have unmet dependencies. linux-image-extra-3.19.0-26-generic : Depends: linux-image-3.19.0-26-generic but it is not installed – AirCombat Mar 4 '16 at 13:52
  • This answer does not fix the problem described. The command in this answer will simply tell you to run apt-get -f install which of course won't work because it will try to write new content to /root which is full. – b_laoshi Mar 6 '19 at 3:01
