Hi there, what is the occurrence of this bug for you? As there's no reproducer, it's quite hard for us to determine the root cause.

it doesn't happen every rebuild or update, and i think has only started recently-ish

is there anything i can do to enable extra logging or something?

i do find that retrying a few times with --keep-going gets the build to succeed eventually

You can do -vvvvv on your Nix builds and we may have more information. You say this started recently, but you are using a Lix 2.92.0 version that was not altered AFAIK.

There's a risk that this came off from another Nixpkgs component or there might be a problem with your system environment? (a network change or something?)

not altered, just installed via the documented way to install without flakes

it very well may be my environment/fault, unlikely a network change as the computer that was run on is connected via ethernet
