What Happened

Started getting the error
ImportError: cannot import name 'read_user_config' from 'dbt.config'
while running sqlfluff on the dbt project.
Important thing to note is: we haven't done any version upgrade in both dbt and sqlfluff.
Other similar issues have been reported in dbt 1.7X only while we are still using dbt 1.6X

Observed Behaviour

dbt-core: 1.6.14
sqlfluff: 2.3.0
python: 3.11

I am experiencing exactly the same error with dbt-core in version 1.7.14. It seems the same breaking changes (from sqlfluff perspective) were released in both 1.6.14 and 1.7.14.

I am experiencing the same issue with dbt-core in version 1.7.14
To resolve this you need temporarily roll back dbt-core to 1.7.13 version

@greg-finley I think the issue is that the new version of sqlfluff where this bug is fixed hasn't been published yet.
The latest version, 3.0.5 was released 2 weeks ago which doesn't seem like it has the fix included

[kzajaczkowski]

Seems to be a dupe of #5841

[anshjain18]

@kzajaczkowski Yes, but that issue was closed and I don't think the problem is resolved yet

[WittierDinosaur]

This is resolved in main - closing as duplicate. I'll create a release candidate now, and we'll try to publish in the next 24 hours

@anshjain18 Upgrading to v3.0.6 fixed the bug for me. Have a go at it?
