It is highly likely that you don't have enough permissions to delete  
the "boot" package. Login as admin and/or root and remove the package.  
Alternatively, if you are admin, you can authorize as root (by  
clicking on the lock in the R GUI toolbar) and perform the upgrade. Be  
sure to de-authorize after you're done (by clicking on the lock symbol  
again).
