Ubuntu: Removing Kernels from grub


My grub has the following versions which I want to remove.

  • Ubuntu, with Linux 4.1.0-rc5-next-20150529
  • Ubuntu, with Linux 4.1.0-rc5-next-20150529.old
  • Ubuntu, with Linux 4.1.0-rc4-next-20150525
  • Ubuntu, with Linux 4.0.0-rc6-next-20150402+
  • Ubuntu, with Linux 4.0.0-rc6-next-20150402+.old

I tried the following methods to remove:

Using Synaptic tool and I have typed the following commands:

uname -r      dpkg --list | grep linux-image       sudo apt-get purge linux-image-x.x.x.x-xyz    sudo update-grub2  

Both of the methods failed to remove the kernel versions.


If your kernel images and headers had been installed from deb packages, not from repositories, you can remove them by

sudo dpkg -r linux-image-x.x.x.x-xyz linux-headers-x.x.x.x-xyz  

But using synaptic is much easier. you will see what are you doing in GUI.
