Install kernel 4.14.13 to combat Meltdown

Linux Kernel

With recent ones security issues generated in recent weeks with regarding the Meltdown and Specter attacks, the big software companies have put in a lot of work to find and solve this.

Meanwhile In Linux, we already have the first fixes that solve these serious security flaws, so we must give ourselves the task of updating the kernel of our system to be protected.

En this new version Linux kernel maintenance The most remarkable from this are the patches that stop Meltdown and Specter attacks, on the other hand, they worked to avoid memory overflow problems, as well as memory allocation.

How to install Linux kernel 4.14.13 maintenance release on Ubuntu 17.10?

Without more the only thing I can say is that this version is extremely important to have it in our system, as it is the solution to current security problems.

It is worth mentioning that the process described here is valid not only for Ubuntu, we can also do it in Linux Mint, Elementary OS, Zorin OS and any other Ubuntu derived system.

For 32-bit versions, We open a terminal and execute the following:

wget -c www.kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.13/linux-headers-4.14.13-041413_4.14.13-041413.201801101001_all.deb

wget -c www.kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.13/linux-headers-4.14.13-041413-generic_4.14.13-041413.201801101001_i386.deb

wget -c www.kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.13/linux-image-4.14.13-041413-generic_4.14.13-041413.201801101001_i386.deb

Already done this, iWe install the packages before downloaded with the following:

sudo dpkg -i linux-headers-4.14.13*.deb linux-image-4.14.13*.deb

Now for 64-bit systems, we download these packages:

wget -c www.kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.13/linux-headers-4.14.13-041413_4.14.13-041413.201801101001_all.deb

wget -c www.kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.13/linux-headers-4.14.13-041413-generic_4.14.13-041413.201801101001_amd64.deb

wget -c www.kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.13/linux-image-4.14.13-041413-generic_4.14.13-041413.201801101001_amd64.deb

Y we finally installed with the following command:

sudo dpkg -i linux-headers-4.14.13*.deb linux-image-4.14.13*.deb

Finally We will only have to restart the computer for the changes to take effect and when we are in Grub, we must make sure that the system starts with the new kernel.

Now if you are a newbie you can avoid doing it manually, you can use this tool that can help you do it for you, the link is this.

    And the bios error for when they repair it or will they simply tell us there is no solution and wash their hands?

    1.    David yeshael said

      The error has already been corrected

      1.    Hector Moreau said

        Good afternoon David.

        Comentas que el error ya fue corregido, pero se supone que habilitaban la descarga el 11/01, pero hasta la fecha nada. Tampoco se da alguna explicación, ni en ubunlog, ni en ogm! ubuntu!, ni en la pagina oficial de Ubuntu.

    This kernel version is hanging all the laptops in our Institute. We have had to disable Lubuntu 16.04 LTS 64 bit updates.
    At home, on my desktop, it works. But the computer hangs when I open my old virtualized Windows XP with VirtualBox. More information in:

      Horror!
      Back in the day, I was referring to 4.13.0-26 (the latest official) for the 16.04 LTS HWE. And now I see that the article said 4.14.13.
      Sorry!

    I am with Kubuntu 16.04.3 and kernel 4.13.0-26, everything patched and working perfectly (no major error or bug), however I must say that I have the same problems as everyone with VirtualBox: although it does not die for me the system, simply the cpu consumption amounts to more than 75% and after a couple of minutes only VirtualBox stops working and not always.

    I get this message: bash: syntactic error near the unexpected element `newline ', the above when entering the first package corresponding to 64-bit based systems How do I correct this to install the packages in Ubuntu 17.10? Greetings!

    Surely they will have to update VirtualBox to accommodate this kernel update

    What is happening with Canonical and Ubuntu?

    Since ubuntu 17.10 cannot be used, it went back to ubuntu 16.04.03. But after installing and updating, among other things, the kernel was updated from 4.10 to 4.13. When I rebooted the pc, I could not search for the programs, because the Ubuntu startup crashed and when I clicked on it, the screen restarted and there was no way to work normally. In other words, the entire dock crashed, it could only work per terminal.

    My Notebook is an HP Pavilion DV5-2247la. 5GHz Intel Core i480-2,66M Processor, 3MB L3 Cache, 2 DDR3 8GB DIMMs, Intel HD Graphics with up to 1696MB Total Graphics Memory, 640GB Hard Drive (5400RPM).

      If you are with 16.04 LTS HWE (16.04.03) the latest official kernel is 4.13.0-31. In my job it is working well on teams that are more than 2 years old. In the newer ones we have problems of assigning IRQs.

      https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/1742626
      https://bugzilla.kernel.org/show_bug.cgi?id=194945#c84

      In the grub menu, advanced options you can start with 4.10. And then you can install grub-customizer to set the boot to 4.10.

      http://ubuntuhandbook.org/index.php/2016/04/install-grub-customizer-ubuntu-16-04-lts/

      We have teams with 4.10 (it is the first measure we take) and since yesterday teams with 4.14.15, http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14.15/

      «What is happening with Canonical and Ubuntu?

      It is not their problem. It is a general issue, which affects all operating systems. Our hardware vendor told me a couple of days ago that he has a lot of Non-Linux machines that won't boot after updating.

      Luck!

    Hi, can kernel 4.14.13 be used with Linux Mint 18.3?

    1.    Josep Pujadas-Jubany said

      I should go. It is an Ubuntu Xenial (16.04), https://linuxmint.com/download_all.php
