 opened [cabal issue #2566](https://github.com/haskell/cabal/issues/2566) about
 disabling downloading in cabal.

+The output from `cabal install --dry-run` doesn't actually give us information
+on which packages need to be downloaded, only the packages to be installed.
+This will be different in the case of local packages. Unfortunately, `cabal
+fetch` won't work for us either, since it accepts different arguments [see
+#2](https://github.com/fpco/stackage-install/issues/2). The compromise we have
+now is to just continue working in the presence of errors during download,
+though a more robust solution would be to check if one of the arguments refers
+to a local package.
 
 ## Why not fix cabal?
