How To Fix dasher: command not found in Ubuntu / Debian / Kali Linux / Raspbian

dasher is:

Dasher is an information-efficient text-entry interface, driven by natural continuous pointing gestures. Dasher is a competitive text-entry system wherever a full-size keyboard cannot be used - for example,

on a palmtop computer
on a wearable computer
when operating a computer one-handed, by joystick, touchscreen, trackball, or mouse
when operating a computer with zero hands (i.e., by head-mouse or by eyetracker).

The eyetracking version of Dasher allows an experienced user to write text as fast as normal handwriting - 25 words per minute; using a mouse, experienced users can write at 39 words per minute.

Dasher uses a more advanced prediction algorithm than the T9(tm) system often used in mobile phones, making it sensitive to surrounding context.

To fix this problem, we can install more using the command below.

sudo apt-get -y install dasher

This command might take some time to finish depending on your machine internet connection.

sudo apt -y install dasher
