Please help me to solve this issue.
Something has changed about the Oracle download process, and nearly every install script on the Internet isn't working. Sit back and relax, this issue started early yesterday morning.
Alternatively you can add Oracles PPA and install from there using apt-get. Follow the commands below.
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
javac -version
This erorr looks like a ppa:webupd8team/java repository problem. The download links are changed now and it's failing to download the JDK.
