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

In Ubuntu unmunge is provided by munge package.

munge is:

MUNGE (MUNGE Uid ‘N’ Gid Emporium) is an authentication service for creating and validating credentials. It allows a process to authenticate the UID and GID of another local or remote process within a group of hosts having common users and groups. These hosts form a security realm that is defined by a shared cryptographic key.

A process creates a credential by requesting one from the local MUNGE service. The encoded credential contains the UID and GID of the originating process. This process sends the credential to another process within the security realm as a means of proving its identity. The receiving process validates the credential with the use of its local MUNGE service. The decoded credential provides the receiving process with a reliable means of ascertaining the UID and GID of the originating process, and this information can be used for accounting or access control decisions.

Clients can create and validate these credentials without the use of root privileges, reserved ports, or platform-specific methods.

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

sudo apt-get -y install munge

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

You can also use apt command to install munge.

sudo apt -y install munge

sudo aptitude install munge
