How To Reset Locale Settings in Ubuntu?

Ubuntu 1

In this article, we will guide you through the process of resetting locale settings in Ubuntu. Locale settings are important as they determine the language and regional settings for your system, such as date, time, and number formats. If these settings are incorrect, it can lead to confusion and even system errors. Let’s dive into the process of resetting these settings.

Quick Answer

To reset locale settings in Ubuntu, you can use the dpkg-reconfigure command to select the locales you want to generate. If that doesn’t work, you can try reinstalling the locales package using the apt-get install --reinstall locales command. If the issue persists, you can manually edit the /etc/default/locale file to ensure the correct locale settings are in place. After making any changes, remember to restart your system for the changes to take effect.

Understanding Locale Settings

Before we begin, it’s important to understand what locale settings are. In Ubuntu, locale settings are used to provide a localized user experience. They control aspects like language, country, and character encoding settings. If you’ve accidentally changed these settings or they’ve been altered by a system update, you may need to reset them.

Checking Current Locale Settings

Before resetting, you might want to check your current locale settings. Open your terminal and type the following command:

locale

This command will display your current locale settings.

Resetting Locale Using dpkg-reconfigure

The easiest way to reset locale settings is by using the dpkg-reconfigure command. Here’s how to do it:

  1. Open your terminal.
  2. Type the following command and press Enter:
sudo dpkg-reconfigure locales

This command will open a dialog where you can select the locales you want to generate. The sudo keyword gives you superuser privileges, dpkg-reconfigure is a command to reconfigure an already installed package, and locales is the package we want to reconfigure.

Use the arrow keys to navigate and the spacebar to select/deselect locales. Press Enter to continue.

Reinstalling Locales Package

If the dpkg-reconfigure command doesn’t work, you can try reinstalling the locales package. Here’s how:

  1. Open your terminal.
  2. Type the following command and press Enter:
sudo apt-get install --reinstall locales

In this command, apt-get install --reinstall tells the system to reinstall the specified package, which in this case is locales.

Manually Editing Locale File

If the issue persists, you can manually edit the /etc/default/locale file. Here’s how:

  1. Open your terminal.
  2. Type the following command and press Enter:
sudo nano /etc/default/locale

This command opens the locale file in the nano text editor with root privileges.

  1. Ensure the file contains the correct locale settings. For example:
LANG="en_US.UTF-8"
LC_ALL=

Replace en_US.UTF-8 with your desired locale. LANG is the system-wide locale setting, while LC_ALL is a more specific setting that overrides LANG and other LC_ variables.

Save the file (Ctrl+O) and exit the text editor (Ctrl+X).

Restarting Your System

After resetting your locale settings, restart your system for the changes to take effect. You can do this by running sudo reboot in the terminal or using the system’s restart option.

Conclusion

Resetting locale settings in Ubuntu is a straightforward process that can be accomplished with a few commands. However, if you encounter any issues or if the problem persists, consider seeking help from the Ubuntu community or support forums. Remember, it’s always important to understand the commands you’re running and the changes you’re making to your system.
