Assume you adopt the 5.4 kernel on amd64. In this condition, it seems to either update Linux kernel at Software Updater and install the specific patches.

1. Verify the system kernel

$ uname -r
5.4.0-42-generic

2. Update the system or install specific kernel patches

1). Update all the system

If you install Ubuntu 18.04, you can find out Software Updater in ShowApplications or update from the popup while your system is opened.

or

2). Install the specific update patches

Build for amd64 with all the linux systems

$ sudo dpkg -i linux-headers-5.4.0-050400_5.4.0-050400.201911242031_all.deb

$ sudo dpkg -i linux-headers-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb

$ sudo dpkg -i linux-image-unsigned-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb

$ sudo dpkg -i linux-modules-5.4.0-050400-generic_5.4.0-050400.201911242031_amd64.deb

3. Install the system again
