libboxfort binary package in Ubuntu Focal arm64

 BoxFort provides a simple API to run user code in isolated processes.
 .
 Although BoxFort provides some kind of security of the parent process from
 spawned sandboxes, a sandbox has by default the same system permissions and
 access than its parent, and is hence, without care, ill-fitted for security
 purposes.
 .
 The main goal of this project is not security, but portable code isolation
 -- if you want complete system isolation, consider using properly configured
 containers.
