gistfile1.txt

## Java
sudo apt-get update
sudo apt-get install default-jdk

## Scala
sudo apt-get remove scala-library scala
sudo wget https://downloads.lightbend.com/scala/2.12.3/scala-2.12.3.deb
sudo dpkg -i scala-2.12.3.deb
sudo apt-get update
sudo apt-get install scala

## SBT
echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2EE0EA64E40A89B84B2DF73499E82A75642AC823
sudo apt-get update
sudo apt-get install sbt

The last two commands

sudo apt-get update
sudo apt-get install scala

are overrunning the scala version I just installed, Redundant IMO

thanks

Thanks
For scala installation, just skip sudo apt-get update
