golang-inet-netstack-dev 0.0~git20211120.8aa80cf2-3 (amd64 binary) in ubuntu jammy

 This is a "fork" of gvisor, extracting out just the "netstack" networking
 bits, which previously were self-contained at
 https://github.com/google/netstack. Why? Because gVisor's go.mod is
 gigantic and causes problems to people trying to use it as a library.
