Ubuntu + scala REPL, Commands not typed on console : <p>I am using Ubuntu 18.04 + Scala 2.11.12 (OpenJDK 64-Bit Server VM, Java 1.8.0_162).</p>

<p>Once I open the scala shell, I am not able to see anything that I type. It gets typed though. </p>

<p>Below is how it is happening when I type <strong><code>println("Hello, world!")</code></strong> at console:</p>

<pre><code>$ scala 
Welcome to Scala 2.11.12 (OpenJDK 64-Bit Server VM, Java 1.8.0_162).
Type in expressions for evaluation. Or try :help.

scala&gt; Hello, world!

scala&gt;
</code></pre>

<p>Any ideas on how we can get through?</p>
