The solution is to run this command:


sudo locale-gen en_US en_US.UTF-8 ms_MY ms_MY.UTF-8


The output :

Generating locales (this might take a while)...
  en_US.ISO-8859-1... done
  en_US.UTF-8... done
  ms_MY.ISO-8859-1... done
  ms_MY.UTF-8... done
Generation complete.



Run the command that produce the error. The error should not appear again.


That's all there is to it. Have fun!

Perl: Terminal does not support AddHistory

If you see the error when running Perl shell, you need to install Term::ReadLine::Perl.




That's all there is to it. Have fun!.
