Does anyone have any advice re: the CI failure here?

In particular, I don't know why the following should be failing like it is (I can't replicate it locally):

cannot import '/nix/store/2jh23bskfidsxs3qcfcahm9kim7d5v7i-source', since path '/nix/store/fg9c5ffzm245w8xpdwryr5k2rgvq5fdr-source.drv' is not valid, at /var/lib/ofborg/checkout/repo/38dca4e3aa6bca43ea96d2fcc04e8229/mr-est/eval-0-gleber.ewr1.nix.ci/pkgs/misc/urbit/default.nix:16:11

@jtobin the error seems to reference 'not listing outputs', and I noticed there are no outputs declared at all. The workings of this thing are a lot more complicated than I have time to figure out, but it would appear each of these might be construed as an output?

@msutherl I think the CI error message might be a bit misleading; the overall check is an "output path comparison," but it doesn't seem to get far enough to actually check any output paths (which shouldn't be problematic). The problem appears to be in importing the derivation retrieved via fetchFromGitHub -- but this seems to be a CI-only issue, because it works fine locally.

I'll take a look for other derivations in nixpkgs that use this kind of pattern and see if they have any information to add.

This now needs to be bumped to 0.8.1

(Closing this one pending resolution of urbit/urbit#1369)
