Now I have new error:

```plaintext
The value 'bullseye-backports' is invalid for APT::Default-Release as such a release is not available in the sources
failed

```

I give up…  
I think it should be noted here that the instructions from the first post not actual at this time.  
Will try with [docker](https://meta.discourse.org/t/install-discourse-for-development-using-docker/102009)
