Solution

  • I have finally figured out the solution.

    Rajarshi is right for the locale problem. However, changing the locale temporarily won't work.

    The package now correctly installed after changing the locale permanently.

    How to check the current locale setting

    1. $ locale

    2. If you notice that LANG is C or empty, probably it is not configured correctly

    How to change the locale setting permanently (Ubuntu)

    1. $ sudo update-locale LANG=en_US-UTF-8

    2. Log out and log in again
