In Ubuntu agda is provided by agda-bin package.

agda-bin is:

Agda is a dependently typed functional programming language: It has inductive families, which are like Haskell’s GADTs, but they can be indexed by values and not just types. It also has parameterised modules, mixfix operators, Unicode characters, and an interactive Emacs interface (the type checker can assist in the development of your code).

Agda is also a proof assistant: It is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Coq, Epigram and NuPRL.

This package provides a command-line program for type-checking and compiling Agda programs. The program can also generate hyperlinked, highlighted HTML files from Agda sources.

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