This is extraordinary .. it presumably is a bug in MacOS.
Running MacOS 10.15.7 on MacBook Pro 2016
I am updating various already installed packges in the usual way:
sudo port upgrade outdated
Everything goes along fine until the software reached gd2.
I then see:
---> Fetching archive for gd2
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2 from
https://packages.macports.org/gd2
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2 from
https://nue.de.packages.macports.org/gd2
---> Attempting to fetch gd2-2.3.3_1+x11.darwin_19.x86_64.tbz2 from
https://ema.uk.packages.macports.org/gd2
---> Fetching distfiles for gd2
At this point the networking on the machine hangs.
I cannot kill the port process. I cannot reach the
offending machine even by ping; I cannot use
the network from another terminal nor browser.
Are you running any third-party firewall? This looks a lot like
<https://trac.macports.org/ticket/61683>, though that was on Big Sur. I
would agree it's certainly an OS bug in any case.
You can try the edits mentioned in the ticket to see if it's the pings
that are triggering the bug. A quick workaround if you just need to get
gd2 installed is to download the distfile manually as per
<https://trac.macports.org/wiki/ProblemHotlist#fetch-failures>.
