[Pulp-list] pulp2 migration: AccessPolicy matching query does not exist

Wed Oct 14 13:52:35 UTC 2020

Thanks for the reply!

I use 'flush' to clear the db, I don't have a 'reset_db' command. Otherwise that's pretty much my process.

The migrate command returns 'No migrations to apply'.

Running 'pulpcore-manager show-migrations' shows that all migrations, including 'guardian.0001/guardian.0002' has checkmarks ([X]).

guardian
 [X] 0001_initial
 [X] 0002_generic_permissions_index

The creation of the migration plan works so I assume my admin user is ok.

I am using an rpm based installation on RHEL8, with

python3-pulp-2to3-migration-0.4.0-1.el8.noarch
python3-pulp-rpm-3.7.0-1.el8.noarch
python3-pulpcore-3.7.1-3.el8.noarch

I don't know what went wrong, but I surrendered and dropped my DB and redid the migrations from scratch - and now it works.
Is there a documented instruction on upgrading existing installations?

//Adam

Hi Adam,

My understanding is that you did the following:
 * stop pulp services
 * pulpcore-manager (or django-admin) reset_db
 * pulpcore-manager migrate
 * pulpcore-manager reset-admin-password --password password
 * start services
 * http POST :/pulp/api/v3/migration-plans/ < your_migraiton_plan.json
 * http POST :/pulp/api/v3/migration-plans/48d03a72-96a1-4d36-9f8b-9a57e97846ef/run/

Sent too early :)
I can't reproduce it so far, so any hints about what can be special about your environment or installation would be appreciated.
Make sure that you have at least one user which has admin privileges and that the guardian migrations ran indeed.
  Applying guardian.0001_initial... OK
  Applying guardian.0002_generic_permissions_index... OK

Hello,

so I updated my pulp3 installation from 3.4 to 3.7 and tried to rerun my pulp2 migration - but it errors out with "AccessPolicy matching query does not exist". Anyone know why?

I flushed my db, reran the 'migrate' job, created a pulp2migration plan (which worked fine) and then tried to run it. Here's the complete error:
