To roll back the kernel, follow these steps:
- Boot into the GRUB menu.
- Select the "Advanced options for Ubuntu" option.
- Select the "Recovery mode" option.
- Select the "dpkg" option.
- Enter the following command:
sudo apt-get install linux-image-generic-hwe-5.0 - Press Enter.
Once the previous version of the kernel has been installed, reboot your computer.
