pacman -Syu error: failed to prepare transaction

Currently, trying to update my packages results in a huge error message that I'm not sure how to fix. This is the output of pacman -Syu:

:: Synchronizing package databases...

At some point I think I had the haskell repository enabled on this machine, but I removed it because it was giving me too many headaches and conflicts. I'm not sure how to go about resetting things so that I can update packages comfortable again.

You should deal with this error - something is wrong. Does that file exist? Is the package installed? Is it missing files?

As for haskell, unless you want to reenable the repository, I guess you need to uninstall those packages. You can then update and reinstall the versions from the standard repositories if you need them.

I checked a couple of those packages, including xmonad, and the versions in the official repos require e.g. ghc 7.6.2-1 so those should work fine with upgrading.
