I want to reinstall Haskell on Debian (in Virtualbox on Windows). So: apt-get remove haskell-platform Deleted all maps with packages in it. apt-get install haskell-platform (installing previous selected ... etc) cabal update All this without errors of warnings. cabal install cabal-install Error: /var/lib/ghc/package.conf.d: openFile: does not exist Why this error? Setup doesn't create this directory?
