Various Options Under Ubuntu Linux To Upgrade Linux Kernel
You can use any one of the following methods:
- Use command-line tools such as apt-get command or apt command
- GUI tool such as Synaptic
- Reboot less kernel patching – Automatic Linux kernel updates for Ubuntu 16.04, 18.04 and 20.04 LTS. Apply critical patches without rebooting and keep your systems secure and compliant using LivePatching.
- Install custom Linux kernel version by compiling it
Let us see all commands and examples in details to upgrade the Linux kernel.
apt-get command – Upgrade Linux Kernel
Open terminal and type the following commands:
$ sudo apt-get update
Now search kernel version:
$ $ apt-cache search linux-image
linux-image-5.4.0-1009-aws - Linux kernel image for version 5.4.0 on 64 bit x86 SMP linux-image-5.4.0-1009-gcp - Signed kernel image GCP linux-image-5.4.0-1009-kvm - Linux kernel image for version 5.4.0 on 64 bit x86 SMP linux-image-5.4.0-1009-oracle - Signed kernel image oracle linux-image-5.4.0-1010-azure - Signed kernel image azure linux-image-5.4.0-26-generic - Signed kernel image generic linux-image-5.4.0-26-lowlatency - Signed kernel image lowlatency linux-image-5.6.0-1007-oem - Signed kernel image oem linux-image-aws - Linux kernel image for Amazon Web Services (AWS) systems. linux-image-azure - Linux kernel image for Azure systems. linux-image-extra-virtual - Extra drivers for Virtual Linux kernel image linux-image-extra-virtual-hwe-18.04 - Extra drivers for virtual Linux kernel image (dummy transitional package) linux-image-extra-virtual-hwe-18.04-edge - Extra drivers for virtual Linux kernel image (dummy transitional package) linux-image-extra-virtual-hwe-20.04 - Extra drivers for Virtual Linux kernel image linux-image-gcp - Google Cloud Platform (GCP) Linux kernel image linux-image-generic - Generic Linux kernel image linux-image-generic-hwe-18.04 - Generic Linux kernel image (dummy transitional package) linux-image-generic-hwe-18.04-edge - Generic Linux kernel image (dummy transitional package) linux-image-generic-hwe-20.04 - Generic Linux kernel image linux-image-gke - Google Container Engine (GKE) Linux kernel image
Now install kernel by explicitly specifying version number such as 5.4.0-1000-aws (this is for AWS EC2 cloud server):
$ sudo apt-get install linux-image-5.4.0-1009-aws
Replace xx.yy with kernel version number. Another option is to apply all patches in a single go as follows to install kernel updates:
$ sudo apt update
$ sudo apt upgrade
Reboot the Linux system using the reboot command/shutdown command:
$ sudo reboot
## OR ##
$ sudo shutdown -r now
GUI tools
This is recommended method for most user. Click on System > Administration > Update Manager > Click on Check button > Apply all updates including kernel.
Latest Ubuntu version kernel updates using GUI
Press the Superkey (Windows key) > Type updater:
You will see the software updater box as follows. Click on the Install Now button:
When a new Linux kernel installed, you will be prompted to reboot the system.
Apply critical Linux kernel patches without rebooting on Ubuntu
We can use Livepatch service that install fixes automatically, without restarting your system which is useful on servers:
- Fixes are applied automatically, without restarting your system
- Reduces downtime, keeping your Ubuntu LTS systems secure and compliant
- Included as part of all Ubuntu Advantage for Infrastructure support packages
- Free version supported for desktop user including up to 3 servers

E: Unable to locate package linux-image-2.6.37.6-generic
E: Couldn’t find any package by regex ‘linux-image-2.6.37.6-generic’
Silas, do apt-cache search linux-image and pick the one from the returned list.
Thanks for helping a Noon out.
I would like to upgrade my 2.6.10 kernel to something newer mainly because there was no driver support for my Claro modem until kernel 2.6.20, as i understand. My problem with apt-get is that it assumes you have an internet connection. I have tried to manually download the package using my Windows connection, and then pointing to that package on my local hard disk through /etc/apt/search.list. But when apt-get reads the package, the package apparently points back to more on-line files to use for information or something.
Am i completely clueless as to how this is supposed to work? This seems almost as senseless as the Claro people telling me to download drivers from the web for my non-functioning modem.
