I want to remove my current kernel after upgradtion of new kernel

I want to remove my current kernel after upgradtion of new kernel

[Anurudh Tiwari]

Hi,

   I am upgrading my machine with new version of os which have newer
version of the kernel.
I have to remove my current kernel(which is going to be old kernel in next
reboot) after up-gradation because i don't want to get prompt to choose the
kernel at booting time.

I tried few methods:
   1 . Try to remove using command ( sudo apt-get purge uname -r )
    -- but after it gives a pop up (dialog box) to select yes or no.(But i
don't to do that because system is automated, user should not interact with
system).

My intention is remove to old kernel at very first time when it reboot(so
no prompt will show to select the kernel by grub)..

Please if you have any best solution for this. please share.

Thanks
Anurudh

I believe you can do `apt-get -y ...` which will confirm any prompts that the user would normally be given.

Wrong list I guess, try askubuntu.com next

or maybe google, you know second result for "linux uninstall kernel" has 
your answers...

http://www.cyberciti.biz/faq/debian-redhat-linux-delete-kernel-command/

You have a debian/ubuntu like system.

Also you should always keep an old kernel in case you notice something 
broken on your new kernel.

[Anurudh Tiwari]

@ Denial : I have tried with -y option. it exempt me from console
confirmation but not from pop-up.

@Malte : I am not using ubuntu. Its a Debian based system.

[Malte Vesper]

Still the link applies to debian as well, look for:

".deb based distro - Debian or Ubuntu Linux"

And i believe the manual steps at the bottom apply to linux in general

I want to remove my current kernel after upgradtion of new kernel

Protip:

You *really* want to keep at least one extra known-working kernel on your /boot
just in case you find a bug in the one you installed. If you don't like getting
prompted, set up grub or grub2 or whatever to boot a default kernel, with a
timeout of 1 second or so, so that if you ignore it, it boots into your default
kernel, but if things go sideways you can boot the old kernel.

And remember - it doesn't have to be a *kernel* bug - if  something decidess to
rebuild your initrd/initramfs, and botches it, you're going to havea bad time
at the next reboot. So you really want a known-bootable kernel/initrd pair
or two on /boot just in case...

Anurudh,

In case your only concern is that you should not wait to make a choice of kernel at boot time then you can change the grub.conf file.

In case of older grub, on installing the new kernel the boot entry for it will be on the top.
So make "default=0" and "timeout=0" in your grub.conf file.

In case of grub-2,
You may need to do some more work through grub config files in /etc and then building new grub.cfg file through grub2-mkconfig command.


Another work-around is to remove all the initrd, System.map and vmlinuz files of unwanted kernels from the /boot location and rebuild grub.conf.
 
Hope this helps!

Adheer
