module not found: org.scala-sbt#sbt;1.1.6

Question

I installed SBT via terminal with following commands:

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

on my Ubuntu 18.04 and with java version:

openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.18.04.1-b11)
OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)

The installation was successful but when I tried to start SBT via terminal, then I've got

https://repo.scala-sbt.org/scalasbt/ivy-snapshots/org.scala-sbt/sbt/1.1.6/ivys/ivy.xml

The root cause is a conflict between openjdk-11-jdk (which is default in Ubuntu 18.04) and sbt packages settings. It has already been fixed in Debian and will be included in Ubuntu shortly. Meanwhile the simplest workaround is to demote your java to version 8. Other solutions employing ca-certificates-java are much more complicated.

First remove conflicting packages:

sudo apt-get remove --purge openjdk* java-common default-jdk
sudo apt-get remove --purge sbt
sudo apt-get autoremove --purge

Check weather you successfully removed all related packages by:

sudo update-alternatives --config java

The system shall prompt you there is no Java available to config, otherwise this workaround fails.

Then reinstall required packages:

sudo apt-get install openjdk-8-jdk sbt

Test by:

sbt compile
