Some people say to unload openssh-client, but Openssh-client is a lot of packages rely on, a lot of xserver of the package are dependent on it, what should be done?

Fix it, first. A dependent version of Openssh-client (Legacy):

sudo apt-get install openssh-client=1:5.9p1-5ubuntu1

And then it's OK to install Openssh-server.
