Installing Scala without using Coursier is straightforward. Follow these directions to install the current version of Scala.
Mac
$ brew install scala
$ scala Welcome to Scala 2.13.3 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_111). Type in expressions for evaluation. Or try :help.
scala> 2+2 res0: Int = 4
scala> ^D

Whenever a new version of Scala is released, brew tends to take a
few extra days before it makes the new version available.
Linux and Windows Subsystem for Linux
Ubuntu
Apt is normally the best way of installing software on Ubuntu.
However, I recommend that you not install Scala this way.
Sadly, Scala support for Debian distributions of Linux, such as Ubuntu, has always been weak at best. The version of Scala available for Debian and Ubuntu is many years out of date (v2.11.12, released November 09, 2017).

Installers
Various installers are provided at scala-lang.org/files/archive.
If you have a Debian-derived distribution like Ubuntu, you could just download a .deb file,
save it, and double-click on it to launch the Ubuntu Software Center.
Scala will then be installed or upgraded.
RPMs, tgzs and other formats are also provided.
When this lecture was last updated, the most recent file was
scala-2.13.14.deb.
You can install the Scala .deb file using a command line like this:
$ cd ~/Downloads
