Debug C app using visual studio code and Vagrant runnig ubuntu

问题

I boot up ubuntu using Vagrant to compile some C code, now i like to debug this code using Visual Studio Code.
How can i setup some kind of remote debug where the compiler and source code and all on the Ubuntu VM
And I only using VSCode from windows?
PS.
This used to work very well with windows WSL linux .
But now i like to achieve the same result with Ubuntu using Vagrant ( using Virtual Box ). Can it be done? UPDATE I tried as suggested but I'm getting error :

my virtual box config from vscode :

Host 127.0.0.1:2222
  HostName 127.0.0.1:2222
  IdentityFile c:/HashiCorp/ubuntu-20.04/.vagrant/machines/default/virtualbox/private_key
  User vagrant

The error :

[13:27:45.945] "install" terminal command done
[13:27:45.945] Install terminal quit with output: The process tried to write to a nonexistent pipe.
[13:27:45.945] Received install output: The process tried to write to a nonexistent pipe.

Yes, as long as you have SSH configured in the VM, you can use the Remote - SSH extension as I detailed in this answer.
