toxic binary package in Ubuntu Focal s390x

 This is a Tox-based instant messenging client which formerly resided in
 the Tox core repository, and is now available as a standalone
 application.
 .
 Tox is a secure and distributed Skype replacement.
 .
 At its heart it’s a client dealing with our core library communicating
 on our own protocol. All communications are encrypted using the peer
 audited NaCl cypto library and this encryption can not be turned off.
 .
 Tox is powered by a distributed network which uses P2P connections for
 chats between people, unlike other Skype replacements no federated
 servers, centralized servers, or supernodes are used.
