$sudo alternatives -install /usr/bin/java java /opt/jdk1.8.0_101/bin/java 2 Next, use command update-alternatives to tell system where java and its executables are installed: You should now move it to a proper folder: $wget -no-cookies -no-check-certificate -header 'Cookie: gpw_e24=http%3A%2F%2Foraclelicense=accept-securebackup-cookie' '' You can either download Oracle JVM by using CA's account from Oracle website to your computer and upload it to the target computer using FTP etc., or use wget to put it there directly.
