Perl: warning: Setting locale failed in Debian and Ubuntu

by

In Debian and Ubuntu, the “perl: warning: Setting locale failed” message is usually caused by a lack of support for the locale that is specified in the system’s environment variables. This can happen when the locale is not installed on the system or when it is not configured correctly.

To fix this issue, you can do the following:

  1. Check which locale is specified in the environment variables by running the command locale. If the output shows that the locale is set to something like en_US.UTF-8, make sure that this locale is installed on your system.
  2. Install the necessary locales by running the command sudo apt-get install locales. Then run sudo dpkg-reconfigure locales to configure them.
  3. Select the locales that you want to use and generate them by using the command
sudo locale-gen en_US.UTF-8
  1. Set the correct locale in the environment variables by running the command export LANG=en_US.UTF-8.
  2. Restart your shell or terminal for the changes to take effect, or you can add this command to your .bashrc or .bash_profile.
  3. You can also set the correct locale in the environment variables by modifying the /etc/environment file, adding the following line
makefile
LC_ALL=en_US.UTF-8
  1. Finally, restart your system or service that uses perl.

After making these changes, the “perl: warning: Setting locale failed” message should no longer appear.

It’s important to note that the above steps are just a general guide and you may need to adjust them to suit your specific requirements.
