I have a server which is running ubuntu with automatic security updates, /boot is now nearly full (93%). Below is the output of dpkg -l "linux-image*"

 ii  linux-image-3.2.0-24-generic                    3.2.0-24.39                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

ii  linux-image-3.2.0-36-generic                    3.2.0-36.57                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

ii  linux-image-3.2.0-38-generic                    3.2.0-38.61                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

ii  linux-image-3.2.0-39-generic                    3.2.0-39.62                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

ii  linux-image-3.2.0-40-generic                    3.2.0-40.64                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

ii  linux-image-3.2.0-41-generic                    3.2.0-41.66                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP 

ii  linux-image-3.2.0-43-generic                    3.2.0-43.68                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

ii  linux-image-3.2.0-44-generic                    3.2.0-44.69                                       Linux kernel image for version 3.2.0 on 64 bit x86 SMP

iF  linux-image-3.2.0-45-generic                    3.2.0-45.70                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

iF  linux-image-3.2.0-48-generic                    3.2.0-48.74                                     Linux kernel image for version 3.2.0 on 64 bit x86 SMP

iU  linux-image-server                              3.2.0.48.58                                     Linux kernel image on Server Equipment.

The server is currently running on 3.2.0-24-generic

 #uname -r 

 3.2.0-24-generic

So my question is can i remove the images inbetween the latest and the running one safely ?

apt-get purge linux-image-3.2.0-36-generic linux-image-3.2.0-37-generic linux-image-3.2.0-38-generic linux-image-3.2.0-39-generic linux-image-3.2.0-40-generic linux-image-3.2.0-41-generic linux-image-3.2.0-43-generic linux-image-3.2.0-44-generic

I understand that i ideally need to reboot the server to bring it up to the latest and then i can clean up the rest but finding a time to reboot with the client is proving .... dificult

Thanks guys :-)

Yes, you can un-install all kernel+header packages, except the currently running kernel+header. This is fine even though you might not have ever booted into those kernels. There are no cross-dependencies between the different kernel packages. Each kernel package only has dependencies for it's own version.

So, if you are currently using the "3.2.0-24-generic" version, I would advise you to remove the following kernel packages and the corresponding "linux-headers" packages:

linux-image-3.2.0-36-generic

linux-image-3.2.0-37-generic

linux-image-3.2.0-38-generic

linux-image-3.2.0-39-generic

linux-image-3.2.0-40-generic

linux-image-3.2.0-41-generic

linux-image-3.2.0-43-generic

linux-image-3.2.0-44-generic

I always keep at least two older kernels, in case I ever need to go back.
