Failed to fix the broken static IP for eth1. Exiting because this will cause problems with other VMs.

* Operating System Version: Ubuntu 20.04.4 LTS
* Deploying via (VirtualBox/VMWare/AWS/Azure/ESXi): Virtualbox
* Vagrant Version (if applicable): 2.2.19

I'm trying to build the lab using Virtualbox on a headless Ubuntu Linux VM. After running `vagrant up` (and verifying all green ticks in prepare.sh), I'm getting the following error from logger while bootstrap is running:
```
logger: [+] python3-pip was successfully installed!
logger: Incorrect IP Address settings detected. Attempting to fix.
logger: [02:19:45]: Failed to fix the broken static IP for eth1. Exiting because this will cause problems with other VMs.
The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
```
I've searched some of the previous issues but not able to find anything directly relevant. I've also tried creating a dummy `eth1` network device with `ip` as my VM doesn't have one, and same issue.
