"Fetching archive" fails for all ports on multiple systems, different networks

Thank for your note.

A quick question: since everything was working up until 1 Apr (I routinely update my macports every monday, and did so as recently as 25 Mar), is there anything you can advise I look to first? The only system updates that I’m aware of in that week were the 10.14.4 and xCode 10.2 updates.

Thanks again,

This is a nonsensical response, since http standards tell us that "403" actually means "Forbidden", while "200 OK" is the response you would get for a normal successful file transfer. Since you get the same nonsensical response from many servers managed by different organizations, it's logical to conclude that the response is not actually coming from those servers but from something intercepting the traffic between you and the servers -- such as a badly-configured proxy managed by your network administrator, or perhaps badly-written antivirus software installed on your computers which is hooking itself into your network stream in an effort to protect you from malicious content, or it could even be malware trying to modify your network traffic for some nefarious purpose. Usually a workaround for circumventing network interference is to use https, since man-in-the-middle content modification is not possible with an encrypted data stream, but your error messages in your previous message showed that even https traffic was being modified; in the https cases, though, the modifications were being detected as a bad ssl stream. The problem is unique to your computers and/or your networks and you'll have to figure out what is modifying your network traffic and how to stop it; there's nothing we can change in MacPorts to fix this.
>> * “sudo port diagnose” reports "Error: currently installed version of Xcode, 10.2, is not supported by MacPorts.  For your currently installed system, only the following versions of Xcode are supported:  10.1 10.0”. Trac #58260 suggests that this is a build problem; i.e., that it occurs after a successful fetch step. Is this understanding correct?

> Xcode 10.2 was released recently and we had not yet added it to the list of approved Xcode versions. Josh has since added it. It's usually fine to use new Xcode versions. As you found in #58260, sometimes new versions of Xcode cause build failures in some ports. As with any bug, these need to be identified and addressed on a case by case basis.
