Unable to upgrade block code

Hello all,

Trying to update the code on a VNX5200 Block only array and getting the this error in USM after transferring the package " List of packages not installable because either one or more packages are required to be installed at the same time or incompatible with already installed packages:
VNX-Block-Operating-Environment"

Seem to be a hang up from a previous update but I cannot see how to clear out the packages, has anyone come across this before?
