Hi,

I've followed the instruction from the upcoming book Real World Haskell to install cabal.

Now, when I enter "cabal update", it answers this:

Downloading package list from server 'http://hackage.haskell.org/packages/archive' cabal: getHostByName: does not exist (no such host entry)

Not sure which libraries you (cabal) is using here. On some debian System there has been a dns issue. You should check wether the tool is using the curl bindings http library and look for this problem in forums of your distro. Maybe try curl <url> That gives That gives: ... The document has moved to http://hackage.haskell.org/packages/archive/ (note the last slash) for me.

Maybe also try adding the ip of hackage.haskell.org to /etc/hosts for a temporary workaround ?

You should also tell us which operating system you are using.

Hi, $ curl hackage.haskell.org gives me the 301 Moved Permanently too. adding 69.30.63.197 hackage.haskell.org to /etc/hosts doesn't change anything. Some info : $ cabal --version cabal-install version 0.5.2 using version 1.4.0.2 of the Cabal library I'm using Kubuntu Gutsy. Thanks, Thu

I received the same error message. After a month I realized that my proxy settings were wrong. (I don't need proxy but the 'http_proxy' variable was present in the shell environment.)

Thank you, that was that (and I've also removed https and uppercase versions). Thu
