Ubuntu + scala REPL, Commands not typed on console

The following thing is working for me.

1. Start sbt

2. Open a scala console via sbt.

   ~$ sbt
       [info] Loading project definition from /home/abhay/project
       [info] Set current project to abhay (in build file:/home/abhay/)
       [warn] sbt server could not start because there's another instance of sbt running on this build.
       [warn] Running multiple instances is unsupported
       sbt:abhay> console
       [info] Starting scala interpreter...
       Welcome to Scala 2.12.4 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_161).
       Type in expressions for evaluation. Or try :help.
       scala> printf("Hello, Abhay!"); 
       Hello, Abhay!
       scala>
   

This is working for me for now.

I am pretty sure its some environment issue. Anyone else facing something similar?

To fix the problem in the current scala repl session run:

import sys.process._
"reset" !

To fix the problem completely removed scala and install it with dpkg (not with apt):

sudo apt-get remove scala-library scala
sudo wget www.scala-lang.org/files/archive/scala-2.11.12.deb
sudo dpkg -i scala-2.11.12.deb
