I have encountered a problem upgrading a worker node (see below). I am removing the existing lcg meta-package and installing the two new glite ones. It seems that boost-g3 version 1.29.1 is required but 1.32.0-6 is being installed. Any ideas? thanks Duncan apt-get remove lcg-WN_torque apt-get install glite-WN glite-torque-client-config Reading Package Lists... Done Building Dependency Tree...
