I get this error while trying to perform this upgrade
column "backup_courses->laststatus" cannot be modified. Dependency found with index "laststatus (laststatus)"
Debug info:
Error code: ddldependencyerror
Error code: ddldependencyerror
Stack trace:
- line 725 of /lib/ddl/database_manager.php: ddl_dependency_exception thrown
- line 582 of /lib/ddl/database_manager.php: call to database_manager->check_field_dependencies()

- line 356 of /admin/index.php: call to upgrade_core()
If I drop the index in question then the upgrade goes through fine, but then I am missing the index once the upgrade is complete.
I feel this is not the correct way to go about it.
Not sure if this is a bug that has existed on our database or in the upgrade code
