Hi,
I think that all database modifications were performed the first time you executed the update, and as it was interrupted, couldn't change the version number, so when running it again tried to perform the changes again.
To ensure all database changes were made look in the table 'reports' and look for the column `is_order_by_asc`, if it is present then all db modifications were made (as this is the last column added by the upgrader), and the only thing you have to do is change the value of 'config/installed_version.php' to 1.4.1
greetings
