how to install plpythonu extension on postgresql 9.3 ubuntu

Question

I had Postgresql 9.3 server on ubuntu installed, but

create extension plpythonu

fail with the error:

ERROR: could not open extension control file "/usr/share/postgresql/9.1/extension/plpythonu.control": No such file or directory

SQL state: 58P01

Postgresql is installed using ubuntu package management system

sudo apt-get install ...

the output of

SELECT * FROM pg_language;

is

internal, c, sql, plpgsql

How can I extend the postgresql so that I can use python ?
