Currently this bug has been reported and has no solution. This is a workaround that has been tested on Ubuntu 20.x:

  1. Edit the file: /etc/default/grub and the following text:

    modprobe.blacklist=vmwgfx


    file: /etc/default/grub

    ..
GRUB_CMDLINE_LINUX_DEFAULT="maybe-ubiquity ipv6.disable=1 modprobe.blacklist=vmwgfx"
...

  2. Update grub

    sudo update-grub

  3. Reboot the server

    sudo reboot

  4. Log in and verify the error is no longer in the error logs:

    sudo journalctl -p err -b
