How To Fix xemacs21-nomule: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu xemacs21-nomule is provided by xemacs21-nomule package.

xemacs21-nomule is:

XEmacs is a full fledged programming language with a mail reader, news reader, info browser, web browser, calendar, specialized editor for more programming languages and other formats than most people encounter in a lifetime, and much more.

This package contains the actual binary used to run XEmacs. It depends on the xemacs21-support package for lisp and etc files, and the xemacs21-bin package for supporting binaries. This binary does not have any of the mule stuff compiled into it. It should be faster than the xemacs21-mule and xemacs21-mule-canna-wnn packages because it does not contain the fairly large bit of code for either the display or input of non-European characters.

This package actually contains one of the three xemacs binaries available. They are xemacs21-nomule, xemacs21-mule and xemacs21-mule-canna-wnn.

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

sudo apt-get -y install xemacs21-nomule

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

You can also use apt command to install xemacs21-nomule.

sudo apt -y install xemacs21-nomule

sudo aptitude install xemacs21-nomule
