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.

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.
