[Haskell-cafe] Cabal error installing Yesod and nehe-tuts on Haskell Platform 2012.2.0.0

[Alexander Foremny]

Hello Eric,

most packages fail to install because zlib-conduit fails to install.
The reason for this -- as can be seen in the last line -- is that the
tar archive from which the source is extracted is corrupted. Simply
run cabal install to try again. I suspect the source archives are
re-downloaded, but maybe someone can correct me if I'm wrong.

Do you have any idea why those tar archives are corrupted? Maybe an
unstable internet connection or even hardware fault?

Regards,
Alexander Foremny
