     Locking is not possible in the directory “/opt/eclipse/configuration/org.eclipse.osgi” '

   Solution:The error occurs when the user does not have the required permission to access the .fileTableLock file. This file is in the configuration directory for Installation Manager. This has to do with folder permission. It's necesary tu run:
   
   chmod -R 777 configuration
