This issue left one of my systems complaining every time I performed an "apt-get" operation.
"apt-get install", "apt-get remove", and "apt-get upgrade" would all print similar errors to this: $ sudo dpkg --no-triggers --remove ghc6 (Reading database ... 134569 files and directories currently installed.) Removing ghc6 ... haskell-utils: timer_create: Invalid argument dpkg: error processing ghc6 (--remove): subprocess pre-removal script returned error exit status 1 haskell-utils: timer_create: Invalid argument dpkg: error while cleaning up: subprocess post-installation script returned error exit status 1 Errors were encountered while processing: ghc6 The fix was to replace haskell-utils (which was broken) with this: #!/bin/bash echo Skipping haskell-utils "$@" Then I was able to remove ghc6 without errors.
