I have been trying to backup for my first time on Ubuntu 16.04 with Duplicati - 2.0.4.23_beta_2019-07-14 and I keep getting this error “System.NullReferenceException: Object reference not set to an instance of an object”
I have tried deleting/repairing the db, I also changed “concurrency-block-hashers” to 1. I have tried excluding to try to narrow down the exception but that didn’t seem to work either, any ideas?
Here is the stack trace
System.AggregateException: One or more errors occurred. —> System.AggregateException: Object reference not set to an instance of an object —> System.NullReferenceException: Object reference not set to an instance of an object
