boot

[jtbrooks101]

How do I clean out the boot. It is full and i can not install update. Is there a way to expand it? Right now it is 217MB

[dino99]

to give you some usefull help, first tell us about your hardware/installation

Do you have a separate /boot partition?

Let's see the output of command mount.

[miegiel]

You probably have old (backup) kernels in /boot/ that are safe to remove (it's recommended to keep at least 1 old kernel).

To view do:

ls -al /boot/
To remove old kernels do for example:

sudo rm /boot/*-3.2.0-40-generic
Where 3.2.0-40-generic is the kernel version you want to remove.

Not necessary to make room, but you might want to cleanup the old kernel entries from the GRUB menu by doing:

sudo update-grub

[Impavidus]

Removing old kernels using the package manager is cleaner than using rm.
sudo apt-get purge linux-image-3.2.0-40-generic
Substitute your old kernel versions. Keep one old kernel as backup. This will update grub automatically.

As Miegiel explained, remove the unwanted and oldest vmlinuz*, initrd.img*, System.map* and config*. after this update the grub with update-grub command.

It will make you some space to update the kernel

The problem is that will not cleanly remove the kernels as it will leave other files dotted around the filing system.

It will also leave the package manager in an inconsistent state. It will have the kernels flagged as installed when they are not.

Although what you and Miegel propose will work, I would advocate doing a proper job and remove them using the suggestion in post #6 or a variation of it using dpkg.

@OP. Please post the output of


dpkg -l | grep -E linux-"headers-|image-"

You can copy and paste it into the terminal and copy and paste the results back here.

It will also show the kernel headers you have installed as they may need cleaning up as well.

Kind regards

[ajgreeny]

I would suggest you use synaptic, which you may need to install first, as it is quite simply the best package manager available and gives you a lot of flexibility that the software-centre does not. Now search for and remove:-



linux-image-3.5.0-17-generic 3.5.0-17.28 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-3.5.0-24-generic 3.5.0-24.37 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-3.5.0-25-generic 3.5.0-25.39 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-3.5.0-26-generic 3.5.0-26.42 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-extra-3.5.0-17-generic 3.5.0-17.28 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-extra-3.5.0-24-generic 3.5.0-24.37 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-extra-3.5.0-25-generic 3.5.0-25.39 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP
linux-image-extra-3.5.0-26-generic 3.5.0-26.42 amd64 Linux kernel image for version 3.5.0 on 64 bit x86 SMP

along with any same numbered header packages. That will leave you with two kernels only and should clean out a great deal of space on your system.

[Paqman]

You also might want to decide if you need to have /boot on a separate partition at all. It's normally only necessary if you are using some unusual filesystem or disk configuration for the rest of your system that the bootloader cannot itself boot. If you've not got some weird setup then having /boot on your normal root partition (as is the default setup) would be simpler and more reliable.

[matt_symes]

Hi

If you want a one liner to remove the kernels, copy and paste this into your terminal. (Captial P below)


sudo dpkg -P linux-image-{,extra-}3.5.0-{17,24,25,26}-generic

I don't understand why no headers were display with that command I posted.

Can you post the output of


dpkg -l | grep linux-headersKind regards

Hi

That looks fine to me. It looks like you have two kernels installed now and that is generally accepted as good practice.

You can double check by running this command again and looking to the numbers next to linux-image and linux-image-extra.


dpkg -l | grep -E linux-"headers-|image-"

You can also look in your boot partition again.


ls -l /boot

Also, to check disk space


df -h

Kind regards

[ajgreeny]

A quick and good way to see how many kernels you have installed and showing in the grub menu, even if you don't normally see that menu is to run
grep "menuentry " /boot/grub/grub.cfg | cut -c 1-100
