How to Install/Upgrade to Kernel 4.0 in Ubuntu, Linux Mint

Last updated: July 28, 2015

Linux Kernel 4.0

Linux Kernel 4.0, a new stable release, has been announced by Linus Torvalds last night. He wrote on the Linux kernel mailing list:

So I decided to release 4.0 as per the normal schedule, because there really weren’t any known issues, and while I’ll be traveling during the end of the upcoming week due to a college visit, I’m hoping that won’t affect the merge window very much. We’ll see.

Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously “small” is all relative. It’s still over 10k non-merge commits. But we’ve definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones).

What’s New in Kernel 4.0:

Linux Kernel 4.0, formerly known as Linux 3.20, features:

  • Live Kernel Patching, ability to install security kernel updates WITHOUT REBOOT.
  • DisplayPort Audio, and better better fan control support for the Radeon DRM driver.
  • Graphics and power-management support for Intel’s Skylake processors
  • Intel Quark SoC support
  • PlayStation PS 3 support.
  • new ARM hardware support, IBM z13 support, better Toshiba laptop support, improved Logitech HID support, and more.

Install Kernel 4.0 in Ubuntu/Linux Mint:

The Ubuntu Kernel Team has made the binary packages for this kernel release, available for download at link below:

Download Kernel 4.0 (.DEB)

First check out your OS type, 32-bit (i386) or 64-bit (amd64), then download and install the packages below in turn:

  1. linux-headers-4.0.0-xxx_all.deb
  2. linux-headers-4.0.0-xxx-generic_xxx_i386/amd64.deb
  3. linux-image-4.0.0-xxx-generic_xxx_i386/amd64.deb

After installing the kernel, you may run sudo update-grub command in terminal (Ctrl+Alt+T) to refresh grub boot-loader.

If you need a low latency system (e.g. for recording audio) then download & install below packages instead:

  1. linux-headers-4.0.0_xxx_all.deb
  2. linux-headers-4.0.0-xxx-lowlatency_xxx_i386/amd64.deb
  3. linux-image-4.0.0-xxx-lowlatency_xxx_i386/amd64.deb

For Ubuntu Server with a graphical UI, you may run below commands one by one to grab packages with wget and install them via apt-get:

For 64-bit system run:

cd /tmp/




sudo dpkg -i linux-headers-4.0.0-*.deb linux-image-4.0.0-*.deb

For 32-bit system, run:

cd /tmp/




sudo dpkg -i linux-headers-4.0.0-*.deb linux-image-4.0.0-*.deb

Uninstall Linux Kernel 4.0:

If for some reason, the new kernel does not work properly for you, reboot into a previous Kernel (Grub boot loader -> Advanced -> select a previous kernel) and run below command in terminal to remove the Linux Kernel 4.0:

sudo apt-get remove linux-headers-4.0.0-* linux-image-4.0.0-*

  1. Terrible How-To. You went directly from downloading the headers and kernel to “After installing the kernel, you may run sudo update-grub command in terminal”. How about the part where you actually install the headers and kernel? Oh that might be to easy in a post about installing a Linux Kernel.

      sudo dpkg -i linux-headers-4.0.0-*.deb linux-image-4.0.0-*.deb

      The author included it just after the wget parts

  2. Install any Ubuntu Linux kernel from:

    I save the needed kernels in my archive folder. In my case, this archive folder is off-line, on a NTFS-compressed partition (Win8.1 format). All my Linux & Windows operating systems have no trouble read-write-install from this off-line drive.

    Double click on the Linux kernel icon. It will auto-install. Do the ALL, then IMAGE & HEADERS, in that order.

    Or move your cursor to the folder where the three files (ALL, IMAGE, HEADER) are kept. Open a terminal in that folder. Then run the command:

    sudo dpkg -i linux-*.deb

    This will work for any Linux kernel, into any Ubuntu-based distro. According to, there are 69 such distros. Of course, the real number is much, much higher than that.

    The above method will also work for all beta & alpha Linux kernels. Grub-customizer will allow a GUI-based way to skillfully put the multi-boot menu in the order you prefer. On my website & my Youtube channel, I’ll show you all, one day, how easy & “simple” this GUI method is.

  3. i am a newbie, and i dont get it:

    sudo dpkg -i linux-headers-4.0.0-*.deb linux-image-4.0.0-*.deb

    we have downloaded two package but installed linux-headers-4.0.0…. linux-image-4.0……

    will we install only 2 packages? where is the linux-headers-4.0.0_xxx_all.deb ?

    or we must install all the packages including all.deb? in turn…?


    • the “linux-headers-4.0.0-*.deb” will automatically select and install both the “linux-headers-4.0.0_xxx_all.deb” and “linux-headers-4.0.0_xxx-generic-xxx_i386/amd64.deb” since both packages’ name started with linux-headers-4.0.0-

      • i got some errors, are those important?:

        Error! Bad return status for module build on kernel: 4.0.0-040000-generic (i686)
        Consult /var/lib/dkms/virtualbox-guest/4.3.18/build/make.log for more information.

        Error! Bad return status for module build on kernel: 4.0.0-040000-generic (i686)

        W: Possible missing firmware /lib/firmware/rtl_nic/rtl8168h-1.fw for module r8169

        but os doesnt seem to be effected badly, it boots and everything works properly….

        • Hal , you have to recompile , virtual box kernel modules , to fix the error.
          And than you have to download rtl8168h-2.fw which is Wifi or Audio driver.
          And your good to go

  4. thanks mate – just ran it all and it works as a charm. nice from you to have the write-up available here.

    Great tutorial very straight forward, never-mind the negative Nancy that`s to stupid to follow instructions.

  6. Hi,

    I installed the kernel however I get a kernel panic and can’t start so I’m logged back in under the old kernel however I can’t remove the new one. I get the following error message:

    E: Unable to locate package linux-headers-4.0.0-*
    E: Couldn’t find any package by regex ‘linux-headers-4.0.0-*’
    E: Unable to locate package linux-image-4.0.0-*
    E: Couldn’t find any package by regex ‘linux-image-4.0.0-*’

    Here’s the output of ls -l on /boot:

    So it looks like it’s installed but apt doesn’t seem to think so. How do I get rid of it?


    • Seems you’ve installed kernel 4.0.2, so the command should be:

      sudo apt-get remove linux-headers-4.0.2-* linux-image-4.0.2-*

      refresh grub boot-loader if previous command doesn’t do it:

      sudo update-grub
      • Didn’t realise I’d done that :D

        I was able to remove the headers however it says it’s couldn’t find the image file to remove. I updated grub however it’s still showing in the grub list. I guess I could edit it out of grub however at the next update grub will put it in again so hoping for something a little more permanent. Have you any other ideas?

    would not compile due to wl mod needed for my wireless card.

  8. When i run
    cpupower frequency-info

    it follows by this:
    You may need to install the following packages for this specific kernel:

    Is there any chance to have it soon?

  9. Guys, I am confused don’t you need to compile the kernel after the install?
    I mean like with the command:

    sudo make && make modules && make install && make modules_install


  10. I get the following errors when I try an installation of the headers DEB file:
