gokube save doesn't work with -n option

[heartofrevel]

When I run below command.

gokube save -l -v -n base

gokube expects that a snapshot with name 'base' already exist and it tries to delete it. And if the snapshot doesn't exist it fails with below error.

$ gokube save -l -v -n base
Warning: you should not snapshot a running VM as the process can be long and take more space on disk
Press <CTRL+C> within the next 10s it you want to stop VM first or press now to continue...
Taking snapshot 'base' of minikube VM...
Error: cannot delete minikube VM snapshot base: not able to delete VM snapshot
(base)

RCA:
The problem is in line 60 of save.go.

err := virtualbox.DeleteSnapshot(savedSnapshotName)
if err != nil {
return fmt.Errorf("cannot delete minikube VM snapshot %s: %w", savedSnapshotName, err)
}

We need to see here if snapshot deletion failed because it doesn't exist or for any other reason.
