# 1) 先裝建套件所需工具
sudo apt-get update
sudo apt-get install -y git devscripts equivs config-package-dev debhelper-compat golang curl

# 2) 抓 host 套件原始碼
git clone https://github.com/google/android-cuttlefish
cd android-cuttlefish

# 3) 一鍵建出並安裝 Debian 套件（會產生 cuttlefish-base_* 與 cuttlefish-user_*）
tools/buildutils/build_packages.sh

# 4) 依序安裝兩個套件（有相依問題會自動補）
sudo dpkg -i ./cuttlefish-base_*_*64.deb || sudo apt-get install -f
sudo dpkg -i ./cuttlefish-user_*_*64.deb || sudo apt-get install -f

# 5) 把自己加到需要的群組（套件會建立 cvdnetwork 群組與 udev 規則）
sudo usermod -aG kvm,cvdnetwork,render "$USER"

# 6) 建議重新開機，讓模組/udev 規則與群組生效
sudo reboot

which launch_cvd
launch_cvd --help
id -nG | grep -E '(^| )kvm( |$|.*cvdnetwork|.*render)' || echo "群組尚未生效，請重新登入/重開機"
ls -l /dev/kvm /dev/net/tun /dev/dri/renderD*  # 權限應分別屬於 kvm / cvdnetwork / render
