Just tried performing a Java update after uploading the 32-bit ARM version of the java update using the following recommended commands:
tar -xvzf jdk-*.tar.gz cp -rf jdk1.8.0_162/* java-8-oracle/ rm -r jdk1.8.0_162 rm jdk-*.tar.gz
All seemed to go ok, I rebooted system from Webmin, and not I cannot access the Mango UI. Webmin is still accessible though. Thinking there was an issue with this version of Java, I used the same above procedure to put it back to Java 1.8 131 as it was before, rebooted via webmin, and I am still not able to access the Mango UI. Any assistance would be appreciated.
