Potentially related to 147425 but i started a new thread since my case was a fresh install, and not a migration.
I tried on two different, clean Ubuntu 18.04 instances (one Linode, one Digital Ocean) to setup a self install via the Docker script. Both times I got the same error.
Print of error
== 20180917024729 RemoveSuperfluousColumns: migrating =========================
WARNING
-------------------------------------------------------------------------------------
An attempt was made to drop or rename a column in a migration
SQL used was: 'ALTER TABLE user_profiles DROP COLUMN IF EXISTS card_image_badge_id'
Please generate a post deployment migration using `rails g post_migration` to drop
or rename columns.
Note, to minimize disruption use self.ignored_columns = ["column name"] on your
ActiveRecord model, this can be removed 6 months or so later.
This protection is in place to protect us against dropping columns that are currently
in use by live applications.
