Vagrant up not working

[Aishwarya9Anand]

Hi,
I have tried to use the Ubuntu on Virtual box in my windows 10 machine for last two days. I have enabled virtualization in BIOS as well but Every vagrant up I'm getting the following error:

Bringing machine 'default' up with 'virtualbox' provider...
==> default: Box 'ubuntu/bionic64' could not be found. Attempting to find and install...
default: Box Provider: virtualbox
default: Box Version: >= 0
The box 'ubuntu/bionic64' could not be found or
could not be accessed in the remote catalog. If this is a private
box on HashiCorp's Vagrant Cloud, please verify you're logged in via
vagrant login. Also, please double-check the name. The expanded
URL and error message are shown below:

URL: ["https://vagrantcloud.com/ubuntu/bionic64"]
Error: SSL certificate problem: self signed certificate in certificate chain

My OS: Windows 10
Vagrant : Vagrant 2.2.7
Virtual Box: Version 6.1.4 r136177

Can anyone please help me out?

Unfortunately, Scotchbox is no longer maintained, and it is using an outdated Ubuntu release which is why you're having problems. Last year I released an updated version called CongacBox which was just updated again today... You can find it on GitHub at https://github.com/reddingwebpro/cognacbox
