@lsix, thanks for your PR! By analyzing the history of the files in this pull request, we identified @NeQuissimus, @copumpkin and @joachifm to be potential reviewers.

[copumpkin]

This seems to have broken a load of stuff: http://hydra.nixos.org/build/51543644/nixlog/1

[copumpkin]

Not sure if upstream changed the hash after release?

[joachifm]

I get the same sha256 here (as the one used in the PR, that is); perhaps a transient error on Hydra? Bad mirror?

Also the changelog notes macos build fixes, has somebody looked into whether the darwin fixes are still necessary?

[copumpkin]

Yeah, I guess the hash is fine here too. Weird 😦

I just ran a test and the darwin-specific stuff (both pieces of conditional behavior) appears to be unnecessary now 😃

[copumpkin]

@joachifm I just got rid of it in master 😄 thanks for pointing it out

[NeQuissimus]

This is so weird... I just downloaded the archive from all mirrors and they are all good, that's not the issue... (and it is still the same as in the PR)

The only thing I can see is that the curl has a download size of 3246 (bytes?) at the bottom. That is way smaller than it should be... if the output is kB, it is way bigger than it should be (~1.3 MiB). I wonder if the 3246 byte file is a 404 or maybe that Cloudflare page you get every now and then when something is not available?!

Some transient error, probably. Hydra jobs are OK after restarting. It's unfortunate that some services just don't return error code correctly.
