Thank you. Reinstalling solved the problem. Eyal Erez There are 10 types of people, those who know binary and those who don't. On Tue, Oct 23, 2018, 17:22 Brandon Allbery wrote:

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,
