<div class="moz-cite-prefix">Ben</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Thanks for that, and here goes:</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">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 class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">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 class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">packet_write_wait: Connection to
10.0.2.1 port 22: Broken pipe</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Searching on the net suggested I try
adding ServerAliveInterval and ServerAliveCountMax into the
sshd_config file - no luck there.<br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">I have tried removing (and purging)
openssh again with no luck.</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">I have also tried disabling ufw in case
there problem was there, no luck.<br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">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 class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">My Linux/Debian knowledge is obviously
pretty limited, and I am not sure what to try next.<br>
</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">What else can I provide that might help
me solve this?</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">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>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">Cheers.</div>

I have just subscribed to this list with this address after
being <br>
a long time lurker using my home email address.<br>
<br>
I am looking for technical assistance after a not quite
successful <br>
recent Debian upgrade (from stretch to buster). Is it
appropriate for me <br>
to do so here? My Linux knowledge is still pretty limited and
I have not <br>
been able to find a solution to the problem through extensive
searches <br>
on the internet.<br>
<br>
If that is a reasonable request, I will detail the problem,
and what I <br>
have tried to do to fix it, in a separate email.<br>
<br>
Thanks in advance.<br>
