#686: cabal install - Codec.Compression.Zlib: incorrect header check ---------------------------------+------------------------------------------ Reporter: Monsikos | Owner: Type: defect | Status: new Priority: high | Milestone: Component: cabal-install tool | Version: 1.8.0.2 Severity: major | Keywords: Zlib Difficulty: normal | Ghcversion: 6.12.1 Platform: | ---------------------------------+------------------------------------------ Comment(by finlay): Having slept on it, and after sending an email to the ISP asking to change their proxy settings, I also had a look at how things are set up on ubuntu packages: {{{ $ HEAD http://archive.ubuntu.com/.../haskell-cabal- install_0.8.0.orig.tar.gz ... Content-Type: application/x-gzip ... }}} and {{{ $ HEAD http://hackage.haskell.org/packages/archive/00-index.tar.gz ... Content-Encoding: x-gzip Content-Type: application/x-tar ... }}} As you can see, the Content-Encoding header is not set on the ubuntu apache server when serving tar.gz files. I guess it would be sensible to not set it on the hackage server either. Note that this is the same problem described on #622. I think the ISPs proxy settings are "wrong", but they are also common, and out of our control. BTW, the ISP is Telecom NZ, with millions of customers, so I don't expect to hear back from them any time soon.
