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

In Ubuntu prefix is provided by libapp-options-perl package.

libapp-options-perl is:

App::Options combines command-line arguments, environment variables, option files, and program defaults to produce a hash of option values.

Furthermore, its special treatment of the “perlinc” option facilitates the inclusion (“use”) of application-specific perl modules from special places to enable the installation of multiple versions of an application on the same system (i.e. /usr/myproduct/version).

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

sudo apt-get -y install libapp-options-perl

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

You can also use apt command to install libapp-options-perl.

sudo aptitude install libapp-options-perl
