sudo cabal update doesn't use http_proxy

[guest]

Hi. I'm just installed ghc and some packages including cabal-install and want to do "cabal update". I have squid proxy in local network. When i use just "cabal update", i see:

================================================================= sparrow@vb:~/.cabal$ cabal update -v3 Downloading the latest package list from hackage.haskell.org Sending: GET  http://hackage.haskell.org/packages/archive/00-index.tar.gz HTTP/1.1 User-Agent: cabal-install/0.10.2 Host: hackage.haskell.org proxy uri host: local_proxy, port: :proxy_port Creating new connection to local_proxy:proxy_port Received: HTTP/1.0 200 OK Date: Tue, 02 Aug 2011 08:51:16 GMT Server: Apache/2.2.9 (Debian) mod_python/3.3.1 Python/2.5.2 Last-Modified: Tue, 02 Aug 2011 04:38:12 GMT ETag: "1bda0be-2de1d4-4a97e50b73500" Accept-Ranges: bytes Content-Length: 3006932 Content-Type: application/x-tar Content-Encoding: x-gzip X-Cache: MISS from local_proxy X-Cache-Lookup: MISS from local_proxy:proxy_port Via: 1.0 local_proxy (squid/3.0.STABLE2) Proxy-Connection: close Downloaded to /home/sparrow/.cabal/packages/hackage.haskell.org/00-index.tar.gz cabal: /home/sparrow/.cabal/packages/hackage.haskell.org/: permission denied sparrow@vb:~/.cabal$ =================================================================

When i try to use "sudo cabal update": ================================================================= sparrow@vb:~/.cabal$ sudo cabal update -v3 Downloading the latest package list from hackage.haskell.org Sending: GET /packages/archive/00-index.tar.gz HTTP/1.1 Host: hackage.haskell.org User-Agent: cabal-install/0.10.2 Creating new connection to hackage.haskell.org cabal: timeout sparrow@vb:~/.cabal$ =================================================================

http_proxy and cabal version: ================================================================= sparrow@vb:~/.cabal$ set | grep HTTP HTTP_PROXY= http://local_proxy:proxy_port/ sparrow@vb:~/.cabal$ cabal --v cabal-install version 0.10.2 using version 1.10.2.0 of the Cabal library sparrow@vb:~/.cabal$ =================================================================

So, if i son't use sudo, cabal go through proxy, but hasn't permissions. And if i use sudo, cabal don't use proxy.

I do not believe that this is cabal-install's fault -- sudo clears the environment by default. Try

sudo -E cabal install ...

instead. (Not guaranteed to work; it depends on the sudo configuration). You can check the effect using

sudo env
sudo -E env

For example, I get

> env | wc -l
55
> sudo env | wc -l
17
> sudo -E env | wc -l
56

Have you tried the suggestion above? Does the problem still persist?
