Hi Peter, > We use EMI1 and I need to install lcg-util 1.13.9 , which is listed > in EMI2 only according to http://emi-dashboard.cern.ch/product/37 . > Is it supported/advised to install this package from EMI2 ? You could give it a try: it may work, or fail because of a dependency that has changed in EMI-2. Why not simply upgrade your WN (?) to EMI-2 altogether?
