  * SECURITY UPDATE: weak diffie-hellman-group1-sha1 kex always preferred (LP: #1728607)
    - 0010-git-c1233679c44-change-order-of-preferred-kex-and-hmac-algorithms.patch
    - 0011-git-b395444062e-Reorder-cipher-and-key-preferences-to-make-more-sense.patch
    Backport of the upstream changes from 2.3.1, matching the OpenSSH 7
    deprecation of diffie-hellman-group1-sha1 (http://www.openssh.com/legacy.html).
    This patch doesn't remove the support of diffie-hellman-group1-sha1 but
    makes it the least preferred kex for backward compatibility
