Check if the version installed is 0.6.1-1 or higher (Kali is not supported out of the box for versions below this). If it’s lower, add these lines to your configuration file: `echo “http://http.kali.org/kali/” | sudo tee /etc/apt-cacher-ng/kali_mirrors` and `echo “http://kali.download/kali/” | sudo tee /etc/apt-cacher-ng/backends_kali`. 3. Create a new configuration file for Kali by running `cat EOF | sudo tee /etc/apt-cacher-ng/kali.conf` and adding the following lines: `# Repository remapping for Kali. See acng.conf and manual for details. Remap-klxrep: file:kali_mirrors /kali ;`. 4. Save and close the configuration files, then restart apt-cacher-ng by running `sudo systemctl restart apt-cacher-ng` in the terminal. 5. Add your user to the sbuild group using `sudo sbuild-adduser $USER` in the terminal. 6. Create a new file called `~/.sbuildrc` with the following lines: `cat ‘EOF’ > ~/.sbuildrc`. This will allow you to customize some settings for your package builds, such as downloading all available architectures and running lintian checks. 7. Save and close the configuration files, then reboot your system by running `sudo reboot` in the terminal. Your sbuild environment is now set up with apt-cacher-ng for faster dependency downloads!
In order to make sure that everything works, theres a few things you can do: run tail -f /var/log/apt-cacher-ng/apt-cacher.log while you run build a package with sbuild. check that the directory /var/cache/apt-cacher-ng/klxrep/ is being populated with packages.
To optimize your kernel module development, use Makefile to automate the building and cleaning process. Here’s an example:

# This script is used to automate the building and cleaning process of a kernel module.
# It also checks that the directory /var/cache/apt-cacher-ng/klxrep/ is being populated with packages.

# Add the kernel module "hello.o" to the object list
obj-m += hello.o

# Build the module using the Makefile in the specified directory
all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

# Clean the module using the Makefile in the specified directory
clean:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

In this example, we’re building the hello.ko module and specifying that it should be built in the current directory (M=$(PWD)). The all target runs make inside the kernel source tree with the appropriate arguments to build our module. The clean target does the same thing but cleans up any intermediate files instead of building them.
To use this Makefile, save it as a file called Makefile in your project directory and run `make` or `make clean`. This will automatically handle all the necessary steps for you!
