Missing files in .ssh directory
<p>I have updated my system with <code>sudo apt-get update</code>.
There was a update of PAM (The Pluggable Authentication Module). I don't remember the message, but there was like a pink screen and I decided to choose <code>no</code> (sorry for that poor explanation).</p>

<p>After that the update continues until something like <code>ssh stop/waiting</code> and then nothing happens. I couldn't cancel this und decided to reboot my Ubuntu Server (14.04 LTS).</p>

<p>After that I cannot connect with a user to this machine with <code>ssh -X user@host</code>. Only the owner can connect. But no other user.</p>

<p>With <code>ssh -v user@host</code> I get the error </p>

<p><code>debug1: Authentications that can continue: publickey,password
Permission denied, please try again.</code></p>

<p>Then I recognized that there are a lot of missing files in my <code>~/.ssh/</code> directory.</p>

<p>There is only the file <code>known_hosts</code>. I think there should be also the files: <code>Readme, authorized_keys, bup, deprec, id_dsa, id_dsa.pub</code>.</p>

<p>Do I have to reinstall ssh?</p>
