How To Fix gnome-flashback-xmonad: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu gnome-flashback-xmonad is provided by xmonad package.

xmonad is:

Xmonad is a minimalist tiling window manager for X, written in Haskell. Windows are managed using automatic layout algorithms, which can be dynamically reconfigured. At any time windows are arranged so as to maximise the use of screen real estate. All features of the window manager are accessible purely from the keyboard: a mouse is entirely optional. Xmonad is configured in Haskell, and custom layout algorithms may be implemented by the user in config files. A principle of Xmonad is predictability: the user should know in advance precisely the window arrangement that will result from any action.

This package comes pre-configured with the default configuration. If you want to build your custom-configured version, make sure that libghc-xmonad-dev is installed and put your configuration in ~/.xmonad/xmonad.hs
