cabal-install cannot download gnuidn-0.2.2

[peti]

Using cabal-install revision 63f1490 from the current master branch, I get the following error trying to fetch http://hackage.haskell.org/package/gnuidn-0.2.2:

$ rm -rf ~/.cabal/packages/hackage.haskell.org/gnuidn && cabal get gnuidn-0.2.2
Downloading gnuidn-0.2.2...
Invalid package gnuidn-0.2.2

That doesn't seem right?

I can reproduce this; cabal update doesn't help and cabal get gnuidn-0.2.1 works fine. Looks like the failure comes from hackage-security.

@23Skidoo it's haskell/hackage-server#488 ; we mostly need a better error message explaining why the package is considered invalid (i.e. because it doesn't pass authenticity validation).

Fixed by haskell/hackage-server#644.
