My mastodon-instance on Bonn.social keeps having problems. Some users report problems following other people from different instances: they get an error 500.
When I tried to rebuild and to get the newest release candidate, there is an error message during the migration:
StandardError: An error has occurred, all later migrations canceled:
Index name ‘index_notifications_on_account_id_and_id’ on table ‘notifications’ already exists
I reported the error on GitHub with more details, but I couldn’t get help there:
Does anyone have some ideas how to solve this problem?
