So I descided to follow this guide:

> [@Install Discourse for development using Docker](https://meta.discourse.org/t/install-discourse-for-development-using-docker/102009):
>
> Developing using Docker Since Discourse runs in Docker, you should be able to run Discourse directly from your source directory using a Discourse development container. white_check_mark Pros: No need to install any system dependencies, no configuration needed at all for setting up a development environment quickly. x Cons: Will be slightly slower than the native dev environment on Ubuntu, and much slower than a native install on MacOS. See also [Developing Discourse using a Dev Container](https://meta.discourse.org/t/developing-discourse-using-a-dev-container/336366) …

I get this error after the “migrating database”  
message:
