The key part is

      NB: ‘containers-0.5.11.0:Data.Map.Internal.Map’

            is defined in ‘Data.Map.Internal’ in package ‘containers-0.5.11.0’

          ‘M.Map’

            is defined in ‘Data.Map.Internal’ in package ‘containers-0.6.0.1’

This suggests your xmonad and xmonad-contrib need to be rebuilt with the new version of containers. Alternately, you will need to use ghc's PackageImports extension to force your xmonad.hs to import Data.Map from containers-0.5.11.0.

Hi,

I've just recently upgraded my system and now I'm getting the following error:

xmonad.hs:454:32: error:

    • Couldn't match type ‘M.Map (KeyMask, KeySym) (X ())’

                     with ‘containers-0.5.11.0:Data.Map.Internal.Map

                             (ButtonMask, KeySym) (X ())’

      NB: ‘containers-0.5.11.0:Data.Map.Internal.Map’

            is defined in ‘Data.Map.Internal’ in package ‘containers-0.5.11.0’

          ‘M.Map’

            is defined in ‘Data.Map.Internal’ in package ‘containers-0.6.0.1’

      Expected type: XConfig Layout

                     -> containers-0.5.11.0:Data.Map.Internal.Map

                          (ButtonMask, KeySym) (X ())

        Actual type: XConfig Layout -> M.Map (KeyMask, KeySym) (X ())

    • In the ‘keys’ field of a record

      In the expression:

        defaultConfig

          {modMask = mod1Mask, keys = myKeys,

           manageHook = manageDocks <+> composeAll myManageHook,

           startupHook = takeTopFocus >> setWMName "LG3D",

           layoutHook = myLayout,

           terminal = "rxvt-unicode -e $HOME/etc/tmux/init",

           workspaces = ["web", "emacs", "dev", ....],

           focusedBorderColor = myActiveBorderColor,

           normalBorderColor = myInactiveBorderColor, borderWidth = 3}

      In an equation for ‘myConfig’:

          myConfig

            = defaultConfig

                {modMask = mod1Mask, keys = myKeys,

                 manageHook = manageDocks <+> composeAll myManageHook,

                 startupHook = takeTopFocus >> setWMName "LG3D",

                 layoutHook = myLayout,

                 terminal = "rxvt-unicode -e $HOME/etc/tmux/init",

                 workspaces = ["web", "emacs", ....],

                 focusedBorderColor = myActiveBorderColor,

                 normalBorderColor = myInactiveBorderColor, borderWidth = 3}

    |

454 |         , keys               = myKeys

    |                                ^^^^^^

My knowledge of Haskell is not good enough to figure this out.  

My xmonad.hs file is available here: https://pastebin.com/rBNUFf1k

Thank you,
