While installing the Ubuntu 20.04 updates during upgrade from 19.10 to 20.04, my screen suddenly went completely white and displayed a message saying

Please logout and try again.

But I could not locate my cursor and so I switched off my laptop. After restarting it again, it was showing an error message saying

Please update the microcode

Why did this happen? How can I solve this problem?

You still can try to fix this interrupted upgrade from a live USB/CD.

To fix from a live USB/CD, boot into the live system then connect to Internet from the live system and open a terminal then follow these steps:

Run:

sudo fdisk -l

And identify your root partition. It could be something like /dev/sda1 then mount it to /mnt like so:

sudo mount /dev/sda1 /mnt/

Then run:

sudo mount --bind /proc/ /mnt/proc/

Then run:

sudo mount --bind /sys/ /mnt/sys/

Then run:

sudo mount --bind /dev/ /mnt/dev/

Then run:

sudo cp /etc/resolv.conf /mnt/etc/resolv.conf

Then run:

sudo chroot /mnt/

Now you are in your original system on the hard disk. Run first:

dpkg --configure -a

Then, update APT like so:

apt update

Then, install upgrades like so:

apt upgrade

When finished run:

exit

Then run:

sudo umount /mnt/dev/

Then run:

sudo umount /mnt/sys/

Then run:

sudo umount /mnt/proc/

Then run:

sudo umount /mnt/

Then reboot to your original system, it should be fixed
