Change sshd configuration:

$ sudo cat /etc/ssh/sshd_config.d/50-cloud-init.conf 
PasswordAuthentication yes
$ sudo sed -i 's@//ports.ubuntu.com@//mirrors.ustc.edu.cn@g' /etc/apt/sources.list.d/ubuntu.sources

sudo apt update -y && sudo apt upgrade -y , then reboot.

Build cuttlefish:

git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish
tools/buildutils/build_packages.sh

Install:

sudo dpkg -i ./cuttlefish-base_*_*64.deb || sudo apt-get install -f
sudo dpkg -i ./cuttlefish-user_*_*64.deb || sudo apt-get install -f
sudo usermod -aG kvm,cvdnetwork,render $USER
sudo apt install -y libvirglrenderer-dev libvirglrenderer1
sudo reboot

Prepare packages:

mkdir cf
cd cf
tar xzvf /media/test/78739a87-9b0b-4935-902f-7d78cc09a076/home/test/cvd-host_package.tar.gz
unzip /media/test/78739a87-9b0b-4935-902f-7d78cc09a076/home/test/aosp_cf_arm64_only_phone-img-11489887.zip

maybe should use --gpu_mode=guest_swiftshader

Install ubuntu 22.04 server, then :

sudo apt update -y
sudo apt upgrade -y
sudo apt install -y ubuntu-desktop  nethogs

Edit:

$ sudo vim /etc/X11/Xwrapper.config

OnBuildingUbuntuKernel

Technology

Before building, enable all of the deb-src items.

Steps:

sudo apt build-dep linux linux-image-unsigned-$(uname -r)
sudo apt install libncurses-dev gawk flex bison openssl libssl-dev dkms libelf-dev libudev-dev libpci-dev libiberty-dev autoconf llvm
sudo apt install git

apt source linux-image-unsigned-$(uname -r)
chmod a+x debian/rules
chmod a+x debian/scripts/*
chmod a+x debian/scripts/misc/*
fakeroot debian/rules clean

Edit the items:

vim debian.xxxx/config/annotations
Change the items you want to change, for example:    
 cat /boot/config-5.4.0-150-generic | grep -i module_force
CONFIG_MODULE_FORCE_LOAD=y
CONFIG_MODULE_FORCE_UNLOAD=y

Edit the configurations:

fakeroot debian/rules editconfigs
fakeroot debian/rules binary-headers binary-generic binary-perarch

Then after building you could get deb generated.
