Ubuntu 22.04 (Jammy Jellyfish)

验证证书的方式

wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-jammy.list http://packages.lunarg.com/vulkan/lunarg-vulkan-jammy.list
sudo apt update
sudo apt install vulkan-sdk

如果想不验证 packages.lunarg.com的证书，使用–no-check-certificate
即第一句命令更改为

wget -qO- https://packages.lunarg.com/lunarg-signing-key-pub.asc --no-check-certificate | sudo tee /etc/apt/trusted.gpg.d/lunarg.asc

下面的Ubuntu 20.04 (Focal Fossa)也一样

如果使用Ubuntu 20.04就需要换一下命令
Ubuntu 20.04 (Focal Fossa)

wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-focal.list http://packages.lunarg.com/vulkan/lunarg-vulkan-focal.list
sudo apt update
sudo apt install vulkan-sdk

还可以多安装点程序

sudo apt install dpkg-dev
sudo apt install libvulkan1-dbgsym vulkan-tools-dbgsym

之后就可以使用vulkan了
ncnn会自动找到vulkan
