Installer Issue 'FileExistsError'

To do this:

  1. Boot the ISO ‘Live’.
  2. Open Konsole
  3. Type: sudo kate /etc/calamares/modules/bootloader.conf
  4. Go to end of file and change the line: installEFIFallback: true
    to installEFIFallback: false
  5. Save the file, close Kate editor, close Konsole
  6. Attempt installation as you normally would

This works on my desktop I hope it works for users with this issue.

Please do let us know if this works or not.
