After installing Ubuntu 16.04, the install procedure laid out my hard drive with the following partitions:

$ df -h
Filesystem          Size  Used Avail Use% Mounted on
...
/dev/sda2           237M  168M   57M  75% /boot
/dev/sda1           511M  3.4M  508M   1% /boot/efi
...

Since then, I now frequently run into the problem that there is not enough space on /boot for kernel updates that the automatic software updater wants to install.

I know how to uninstall old kernels; that is not the problem. The problem is that I now have to do it this often. I cannot recall ever experiencing this before in my many years running Ubuntu. Could it be that it is a mistake in the partition lay-out and that Ubuntu perhaps originally intended some of the image files to be installed in /boot/efi instead which seems to stay almost unused despite its larger size?

Can I safely shrink the /boot/efi partition and enlarge the /boot partition to make more room for kernel updates so that I don't have to clean out so often?

  • You might have to reinstall Ubuntu for that- remember, choose your mb's wisely. – boomt14 Jun 15 '16 at 6:43
  • the best way is reinstall system. but may be you can try use 'resize2fs' command, backup your data first! – zayn Jun 15 '16 at 7:41
  • @Edity-deleted- I just chose to let the Ubuntu installer partition the hard drive automatically, trusting it would make a sane choice, but apparently it didn't. – Thomas Arildsen Jun 16 '16 at 20:08

Please,please backup your data if you choose to do this, i don't hold any liability for your data damage.

You will need.

-A Live USB/CD-drive to boot up with.

Lets begin!

  1. Use Ubuntu on Try Ubuntu without Installing option.

  2. Gparted should be present, if not use sudo apt-get install gparted

  3. Hunt down your partition. Yeah I'm not a ubuntu expert, so it might be dev/sda1.

  4. RClick on your drive and choose resize/move

  5. insert elevator music here drag how much you need,

  6. click ok (or resize/move)

Now since the changes won't take immediently to use, you need to hit the tick button to confirm the changes.

Now you can have a great day knowing your computer has been extended.. :D
