Hello, I am new to haskell, and I'm trying to get cabal to download and install packages for me. However, it seems to fail to download packages. Having cabal act on already installed packages seems to work fine. Here is the end of the output: cal@romeo:~$ cabal install haddock ... selecting unix-2.3.0.0 (installed) selecting ghc-paths-0.1.0.5 (hackage) and discarding ghc-paths-0.1, 0.1.0.1, 0.1.0.2, 0.1.0.3 and 0.1.0.4 In order, the following would be installed: ghc-paths-0.1.0.5 (new package) haddock-2.4.2 (new package) Downloading ghc-paths-0.1.0.5... GET http://hackage.haskell.org/packages/archive/ghc-paths/0.1.0.5/ghc-paths-0.1.... Sending: GET /packages/archive/ghc-paths/0.1.0.5/ghc-paths-0.1.0.5.tar.gz HTTP/1.1 User-Agent: cabal-install/0.6.2 Host: hackage.haskell.org proxy uri host: , port: Creating new connection to cabal: Error: some packages failed to install: ghc-paths-0.1.0.5 failed while downloading the package. haddock-2.4.2 depends on ghc-paths-0.1.0.5 which failed to install. I first guessed that cabal was tripping up over some environment variable, but it seems that $http_proxy is unset: cal@romeo:~$ set | grep -i http | xclip http_proxy= Can anyone provide some advice as to what is likely to be going wrong? Thanks, Cal
