How to Fix Missing bcm43224 Firmware in Kali

I’m running Kali on an OLD Macbook Air. I ran an update today and was having trouble completing the initramfs update so I removed the old kernels and rebooted.

Of course when the system came back up, the wifi adapter wasn’t working. Missing firmware. The Macbook is using a Broadcom 43224 device.

After some troubleshooting and internet researching, I found I needed to install a brcmsmac package. Thanks to this debian wiki page. I grabbed an Alfa USB wireless adapter to get online in the meantime.

These are the commands I ran. Simple fix, just using apt-get and modprobe.

sudo apt-get install firmware-brcm80211
modprobe -r brcmsmac
modprobe brcmsmac

The wifi adapter came back up after that. Just leaving this here in case it can help someone else too.

How To Install OVFTool on Ubuntu 20.04 with Python3

Since I use terraform to clone and provision VMs on ESXi, I need to use VMWare’s ovftool. However, I’ve been having errors lately. The OVFTool wants to install using python2, and I keep getting syntax errors. Seems like it’s using my Python3 install and I can’t get it to install.

For this particular issue with the failed installation on Ubuntu 20.04, this means extracting the ovftool files from the installation .bundle, copying them to /usr/bin/ and configure an alias for the ovftool executable.

How To Fix Ubuntu command-not-found sqlite errors

For my home network, I’ve been trying to transitioning to using an Infrastructure-as-code (IaC) approach based on a terraform and the terraform esxi provider plugin. I maintain a few “gold images” of the base line systems, then clone and provision as needed.

I’m not sure where the root cause of this issue is, but I’ve seen it pop up a few times now so I figured I’d write down how I’ve fixed it.
