uhd @3.15.0.0_2: Downloader raised an unhandled exception: HTTPConnectionPool(host='127.0.0.1', port=5683): Max retries exceeded with url:

[nero152 (Glen Roberts)]

I have a fresh install of MacPorts on my MacBook Pro, which is running Catalina (version 10.15.4). Prior to installing MacPorts, I followed all of the prerequisites like verifying that I have xcode and xcode command line tools, as well as acknowledging the license.

When I tried to install gnuradio, I received an error regarding uhd. I have attached the error log. Any assistance would be greatly appreciated.

Accessing that failed URL in a browser works for me. Maybe there was a temporary server problem on their end. You could try again.

This also points out a bug in the uhd port: it tries to fetch things at destroot time. Ports should only fetch during the fetch phase, and should ideally do so by using the standard MacPorts machinery for fetching.

[michaelld (Michael Dickens)]

@nero152 : The internet path to the images server comes and goes depending on where you are accessing it from in the world; it is, broadly speaking, fairly reliable inside the USA, and less so internationally. The most reliable path forward is to just try the install again ("sudo port install uhd"); both "cmake" and the images downloader will pick up where they left off, overwriting files if/as necessary. If that fails, you can always clean the install ("sudo port clean uhd") and try it again.

[michaelld (Michael Dickens)]

@ryandesign : I agree that downloading files in the "fetch" phase is ideal. It works for the vast vast vast majority of ports. I've never found a -reliable- way to get it to work with UHD. For UHD to work properly, it requires these images. The images are traditionally fetched once UHD is installed, by the images downloader, to make sure they are compatible with the just-installed UHD; incompatible images are checked for during runtime, and UHD will not function if the images aren't compatible. I will look into this issue again, as it's been a while & maybe things have changed & hence it might be doable without too much challenge to get the inventory file & then download the images. No guarantees.

[nero152 (Glen Roberts)]

@michealld : I tried to install uhd again after issuing the "sudo port clean uhd" command. Same error... I tried navigating to the listed URL (​http://files.ettus.com/binaries/cache/x3xx/fpga-fde2a94eb/x3xx_x310_fpga_default-gfde2a94e.zip) from a browser and the connection was refused from there as well.

However, if I issue a wget command for the URL, I am able to download the zip file.

[michaelld (Michael Dickens)]

Can you try the URL directly again but using "https" instead of "http"?

Both work for me, but we've seen some OSs have networking issues when using the latter. I believe this behaviour is fixed (all moved to the former) in the next UHD release.

[nero152 (Glen Roberts)]

When using a web browser, I am able to download the zip using "https", not "http". With the terminal, I can download both.

[michaelld (Michael Dickens)]

Excellent. Let me see about adding that fix into the current UHD port ... it should take care of the issue!

[michaelld (Michael Dickens)]

Added in < ​https://github.com/macports/macports-ports/commit/93b27caf80c138765d30a96d4b96d2c36bd1014a >. Please update your ports and try installing UHD again & hopefully this will do the trick!

[nero152 (Glen Roberts)]

That worked. Thanks! UHD installed.

[michaelld (Michael Dickens)]

Great! You're welcome & thanks for reporting back!
