Hello Jeffrey, I have the exact same email authentication error this thread amend posted. I currently used bitnami console manage EC2 at AWS service. I tried to hit the update button and nothing really happens. I was wondering if there is any way to upgrade to the new changes so my email service can work, thanks! Ivan ---

I am not aware of an “update button.” Have you followed the instructions on [our Product Upgrades documentation page](https://github.com/dreamfactorysoftware/dsp-core/wiki/Product-Upgrades)? ---

If you know you have not intentionally / manually changed any files locally, you should be fine to choose ‘y’ to continue. (Sometimes when a package is updated, the files may have changed permissions or get moved around in the source, making the old installed version look like it was modified according to git, even though it was not.) For upgrades, unless you’re manually making changes locally, you will essentially always need to choose “yes” on these prompts. Once you allow composer update to finish, the git operations should complete without aborting. ---

There is no upgrade path from 1.9 to 2.0 If you’re just trying to upgrade a 2.0 instance to the latest code revision, use the instructions on the 2.0 documentation here: [https://wiki.dreamfactory.com/DreamFactory/Installation#Windows](https://wiki.dreamfactory.com/DreamFactory/Installation#Windows) When you run git stash what fails?
