(solved) Fails install in Kali

[RChadwick7]

I'm trying to install the driver on Kali in a VMWare VM. It's a direct download, with updates installed.

Linux kali 5.17.0-kali3-amd64 #1 SMP PREEMPT Debian 5.17.11-1kali1 (2022-05-30) x86_64 GNU/Linux EFI variables are not supported on this system Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 004: ID 0e0f:0008 VMware, Inc.

When I try to install the driver, the script throws an error:

Any ideas? Thanks!

[morrownr]

A quick and dirty look tells me the package bc is not installed.

/bin/sh: 1: bc: not found

I may need to investigate why that all of the sudden that came up.

Nevertheless, you can install it via:

$ sudo apt install bc

You will want to run the following to clean things up before trying again:

$ sudo ./remove-driver.sh

I am interested in what version of gcc you are using and what iso of Kali you installed if you would be so kind as to provide that information.

Let me know.

status?

[KoryMac]

I manually installed bc and the install finished properly (was having this same issue).

[morrownr]

I thought I had this sorted out long ago but stuff happens and it does not cause problems if we tell apt to install something that is already installed anyway. I have revised the installation steps in README to add bc for Kali.

Thanks for the help fixing this.
