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

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

xemacs21-mule 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 has been compiled with support for mule, but no input extensions.

Mule is the extension to (x)emacs that allows for the display of non-European characters (for example Japanese and Korean characters). This version of the package is mainly useful for only the display and reading of international characters. It does not have any mechanism for entering non-European characters (see the xemacs21-mule-canna-wnn package for that).

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-mule

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

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

sudo apt -y install xemacs21-mule

sudo aptitude install xemacs21-mule
