This is extraordinary .. it presumably is a bug in MacOS.<br>
<br>
Running MacOS 10.15.7 on MacBook Pro 2016<br>
<br>
I am updating various already installed packges in the usual way:<br>
<font color="blue">sudo port upgrade outdated</font><br>
<br>
Everything goes along fine until the software reached <font color="blue">gd2</font>.<br>
I then see:<br>
<br>
<font color="blue">---> Fetching archive for gd2<br>
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2
from <a href="https://packages.macports.org/gd2" target="_blank" rel="noreferrer">https://packages.macports.org/gd2</a><br>
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2
from <a href="https://nue.de.packages.macports.org/gd2" target="_blank" rel="noreferrer">https://nue.de.packages.macports.org/gd2</a><br>
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2
from <a href="https://ema.uk.packages.macports.org/gd2" target="_blank" rel="noreferrer">https://ema.uk.packages.macports.org/gd2</a><br>
---> Fetching distfiles for gd2</font><br>
<br>
At this point the networking on the machine hangs.<br>
I cannot kill the port process. I cannot reach the<br>
offending machine even by <font color="blue">ping</font>; I cannot
use<br>
the network from another terminal nor browser.<br>
<br>
Obviously, this is not a problem with Macports (is it?)<br>
I mean, how can an attempt to retrieve a package from<br>
some remote location actually hang my networking.<br>
<br>
This problem is completely replicable on my machine. I reboot the
machine<br>
and everything is back to normal. Then fire up <font color="blue">port</font>
again<br>
.. get same messages as above.. then hangs again. I<br>
have tried waiting for two hours before retrying --<br>
same result. I have tried it on a different box<br>
but that package was not needed. I will work on it <br>
further tests.<br>
<br>
It seems wildly improbable, but has anyone else experienced<br>
this or anything like it? I am completely baffled.<br>
(Except for one thing: the quality of MacOS has been in decline<br>
now since the demise of Jobs)<br>
