Bug Description

I'm running Ubuntu 12.04 beta ("Precise"), and stumbled into this bug:

   http://www.haskell.org/pipermail/haskell-cafe/2011-August/094883.html

when a new version of the bytestring library was added to Hackage. Any cabal operation fails with

   Reading available packages...
   Resolving dependencies...
   cabal: Couldn't read cabal file "bytestring/0.9.2.1/bytestring.cabal"

The workaround from the link above, works:

   tar -f ~/.cabal/packages/hackage.haskell.org/00-index.tar --delete bytestring/0.9.2.1

Although hopefully, we'll avoid packages that trigger this bug in the future, it would be better if Ubuntu would upgrade the cabal version to a newer one that doesn't display this behavior.

Thanks for the report. Looks like this is a problem in the cabal library (provided by ghc) as opposed to the tool itself. So I'm reassigning. I'm thinking about shipping GHC 7.4 with Precise anyway, so if that happens then we'll get the fix from there (provides Cabal 1.14.0.0).
