I can't install Ubuntu in my Dell laptop using a bootable pendrive

system-installation

Can anyone help me with this error? I get this error after plugging in my Ubuntu pendrive:

error: symbol 'grub_register_command_lockdown' not found.
error: symbol 'grub_register_command_lockdown' not found.

Press any key to continue...

If you used Rufus to create the installation USB stick, then you’ll need to download version 3.14 (or newer) and recreate the media. Otherwise, there is a security patch that will need to be installed.

This comes from the developer of Rufus who recently provided a bit of detail about why the issue is happening 😕
