Bug Description

Ubuntu LTS, 16.04 and 14.04, are shipped with a 0.6.X version of ssh, which does not support some recent KEX algorithms.

Some ssh servers are disabling older KEX algorithms. For example, pfSense 2.3.2 already refuses all KEX algotithms of libssh 0.6.X:

In ubuntu this affects Remmina which cannot connect to pfSense 2.3.2, as reported here:
