            <div>Ben</div>
            <div><br>
            </div>
            <div>Thanks for that, and here goes:</div>
            <div><br>
            </div>
            <div>We have two Debian systems here, along with a bunch of
              Kubuntu and Windows systems. Early last week I upgraded
              the second of our Debian systems from stretch to buster. A
              few days earlier, I had upgraded the other Debian system,
              also from stretch to buster. That first upgrade went fine
              and everything is working as expected.</div>
            <div><br>
            </div>
            <div>However the second (of course the more important
              system) did not upgrade correctly. It is mostly ok, but I
              am unable to ssh in to that machine. When I try to, I get
              this:</div>
            <div><br>
            </div>
            <div>packet_write_wait: Connection to 10.0.2.1 port 22:
              Broken pipe</div>
            <div><br>
            </div>
            <div>Searching on the net suggested I try adding
              ServerAliveInterval and ServerAliveCountMax into the
              sshd_config file - no luck there.<br>
            </div>
            <div><br>
            </div>
            <div>I have tried removing (and purging) openssh again with
              no luck.</div>
            <div><br>
            </div>
            <div>I have also tried disabling ufw in case there problem
              was there, no luck.<br>
            </div>
            <div><br>
            </div>
            <div>Stopping ssh and sshd services and installing dropbear
              allows me to login to the machine, and I can perform
              normal file operations. However, this machine collects and
              distributes our emails for all users on our LAN and the
              other machines can't access the machine. There is another
              (off-site) Debian machine that does an important overnight
              folder sync which it is currently unable to do as it can't
              ssh in.<br>
            </div>
            <div><br>
            </div>
            <div>My Linux/Debian knowledge is obviously pretty limited,
              and I am not sure what to try next.<br>
            </div>
            <div><br>
            </div>
            <div>What else can I provide that might help me solve this?</div>
            <div><br>
            </div>
            <div>Sorry to be a bit longwinded and possibly not precise
              enough in my description of the problem. Thanks in advance
              for any suggestions, advice or assistance.</div>
