Ubuntu – Failed ubuntu 20.04 installation upgrade

20.04system-installationupgrade

While installing the ubuntu 20.04 upgrades, my screen suddenly went completely white and displayed a message saying ” Please logout and try again “. But, I could not locate my cursor and switched off my laptop. After restarting it again, it was showing an error message saying ” Please update the microcode”. Why did this happen? Can someone please help me 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:

    sudo dpkg --configure -a
    

    Then, update APT like so:

    sudo apt update
    

    Then, install upgrades like so:

    sudo 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
