Cause:-
missing write permissions in etc/oraInventory/locks the user who is running adpreclone.pl

Solution
1/ Give write permissions to the user running adpreclone.pl to /etc/oraInventory/locks directory
2/ Ensure you are able to "touch" a file in this location before retrying adpreclone.pl
3/ Then re-run adpreclone.pl
