That's to be expected, given: openssh (1:7.1p1-1) unstable; urgency=medium* New upstream release (http://www.openssh.com/txt/release-7.0, closes:
#785190):
- Support for the legacy SSH version 1 protocol is disabled by

at compile time.
- Support for the 1024-bit diffie-hellman-group1-sha1 key exchange
is
disabled by default at run-time. It may be re-enabled using the
instructions at http://www.openssh.com/legacy.html
(from early December 2015)
