debspawn is a tool to build Debian packages. For alternative tools, see Package build tools. For more general package maintenance, see Package maintenance tools.

debspawn uses systemd-nspawn for isolation. It caches .debs by default and uses Zstd compression for base images, making it faster than the default configurations of many similar build tools. See the upstream README.md for more details.

Install debspawn: 

$ sudo apt install debspawn
