Endev-3.2.9 stuck at installation (Virtualbox)

I am booting this up for the first time by following this guide using the following hardware/software.

  • Linux Mint 20 LTS (Cinnamon)
  • Acer C720P Chromebook
  • Virtualbox with VDI image

It’s been hanging on ‘starting endev-3.2.9’ for over 15 minutes. Please advise. Thank you!
