Cap production deploy - Rails 6 - Failing

Trying to deploy a rails 6 application to a Digital Ocean droplet.

I run cap production deploy and it fails with this error:

(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Command::Failed: rake exit status: 256

Any idea what causes this? The gem dependencies are all satisfied and the server is running the same versions of ruby, rails and ubuntu as I have on my dev box.

Solution

  • I had endless problems deploying this app. Credentials problems, sassc nightmares and more. In the end, I started a new 5.2.2 project, copied in the controllers, models, migrations, views, routes, etc., and changed a few instances of [6.0] to [5.2]. First try deployed perfectly and the app is now live. I can only assume there is something not fully working with my rails 6 install. Thanks for your replies, guys.
