juju-1-default 1.25.5-0ubuntu3 (s390x binary) in ubuntu xenial

 Through the use of charms, juju provides you with shareable, re-usable,
 and repeatable expressions of devops best practices. You can use them
 unmodified, or easily change and connect them to fit your needs. Deploying
 a charm is similar to installing a package on Ubuntu: ask for it and
 it’s there, remove it and it’s completely gone.
 .
 This package contains a symlink for legacy juju-1 tooling that requires
 the /usr/bin/juju binary to point to juju-1, rather than juju-2.0.
 .
 No other packages should depend on this package.
