golang-github-yggdrasil-network-yggdrasil-go-dev 0.4.7-1 (s390x binary) in ubuntu lunar

 Yggdrasil is an early-stage implementation of a fully end-to-end encrypted
 IPv6 network. It is lightweight, self-arranging, supported on multiple
 platforms and allows pretty much any IPv6-capable application to
 communicate securely with other Yggdrasil nodes. Yggdrasil does not
 require you to have IPv6 Internet connectivity - it also works over IPv4.

 This package contains the libary for use in other Go programs.
