Error found when installing scala in ubuntu

Question

I am installing scala in ubuntu 15.10. When I use the command: apt-get install scala, it shows this output:

Err http://tn.archive.ubuntu.com/ubuntu/ wily/universe scala-library all     2.11.6-1
  404  Not Found [IP : 91.189.88.161 80]

E: Impossible de récupérer certaines archives, peut-être devrez-vous lancer apt-get update ou essayer avec --fix-missing ?

How can I resolve it ? Any help please

Answer 1

You can download archive, unzip it

wget https://downloads.lightbend.com/scala/2.12.3/scala-2.12.3.tgz
sudo cp scala-2.12.3.tgz /usr/local/share/scala-2.12.3.tgz
cd /usr/local/share
sudo tar xzvf scala-2.12.3.tgz
sudo rm scala-2.12.3.tgz

and update PATH

nano ~/.bashrc

adding lines

export SCALA_HOME=/usr/local/share/scala-2.12.3
export PATH=$PATH:$SCALA_HOME/bin

Now Scala should work

$ scala
Welcome to Scala 2.12.3 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_144).
Type in expressions for evaluation. Or try :help.
