If you are unable to update a plugin via the WP admin console, then you can do the update manually. Download the zip file to your local hard drive and extract it. Then, from the command line, do the test run first:

|
cd {extracted_plugin_directory} rsync -av --dry-run --delete ../{extracted_plugin_directory}/ theHost:/volumes/www/theSite/wordpress/wp-content/plugins/{extracted_plugin_directory}/ |
*Make sure to use the trailing slashes with rsync for proper operation […]

PROBLEM DEFINITION Bamboo Catalina error found in catalina.out:
|
|
-Djava.endorsed.dirs=/volumes/data/bamboo/current/endorsed is not supported. Endorsed standards and standalone APIs in modular form will be supported via the concept of upgradeable modules. Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit. |
SOLUTION SUMMARY Correct by using Java 8 instead. Do it manually using alternatives –set, or interactively using alternatives –config. MANUAL PROCEDURE – two steps, one for java and one for javac
|
|
alternatives --set java /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java alternatives --set javac /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/javac |
