Now isn't this a very precise error message? Which other hints do you need?

Your whole approach seems  overkill  to  me.  Why  don;t  you  simply
include  a  "saveenv"  command  in your update script? As long as the
environment is not shifted (which  seems  unlikelyin  your  case)  no
other changes are needed.
