tahoe-lafs binary package in Ubuntu Xenial s390x

 Tahoe, the Least Authority File Store, is a distributed filesystem that
 features high reliability, strong security properties, and a fine-grained
 sharing model. Files are encrypted, signed, erasure-coded, then distributed
 over multiple servers, such that any (configurable) subset of the servers
 will be sufficient to recover the data. The default 3-of-10 configuration
 tolerates up to 7 server failures before data becomes unrecoverable.
 .
 Tahoe offers "provider-independent security": the confidentiality and
 integrity of your data do not depend upon the behavior of the servers. The
 use of erasure-coding means that reliability and availability depend only
 upon a subset of the servers.
 .
 Tahoe files are accessed through a RESTful web API, a human-oriented web
 server interface, and CLI tools.
