Stop ubuntu from automatically upgrading kernel

  • 772

I am using ubuntu 20.04 and the default kernel version is 5.4.0-42 and 5.4.0-58. For some reason, I have upgraded my kernel to 5.8.0-36 several days ago with the command sudo apt install linux-image-5.8.0-36-generic. But now the kernel version has automatically upgraded to 5.4.0-40 and I was not notified. How can I stop the automatic upgrading?

  1. If you will stay with kernel branch 5.4

    sudo apt install linux-generic

    boot in the new installed kernel.

    identify

    dpkg -l | egrep linux-'[g|i|h|m]'

    Kernel relevant packages and remove any which point to hwe-20.04 and kernel branch 5.8. like

    linux-generic-hwe-20.04 linux-headers-5.8.0-40-generic linux-headers-generic-hwe-20.04 linux-hwe-5.8-headers-5.8.0-40 linux-image-5.8.0-40-generic
  linux-image-generic-hwe-20.04 linux-modules-5.8.0-40-generic linux-modules-extra-5.8.0-40-generic
