Hi,

I still can’t upgrade my pulp2 to pulp3 under Katello. I have tried several times, thinking that one day a package update might solve it. This time the error is different:

Pulp2to3MigrationClient::ApiError: Error message: the server returns an error

Help is highly appreciated. :slight_smile:

Hi @Oliver_Weinmann

Do you have the python3-pulp-2to3-migration package installed?

Hi,

yes the package is installed:

[root@katello ~]# rpm -qa | grep python3-pulp-2to3-migration
python3-pulp-2to3-migration-0.11.4-1.el7.noarch

It is really strange. I have the feeling the upgrade fails every time with a different error. I rebooted the katello host and currently the upgrade is running for over 10 minutes. I will wait and see if it completes this time.

[root@katello ~]# foreman-maintain content prepare
Running Prepare content for Pulp 3
================================================================================

Of course it failed again after 20 minutes. I wonder If I’m affected by this bug:

https://pulp.plan.io/issues/8275

We do have SLES 15 repos. I will try to remove the repos and re-try the upgrade.

Ok, I removed all SLES 15.x repos and all debian repos, but the upgrade still fails… Now I get the error:

ForemanTasks::TaskError: Task 5ad0f9a2-266b-4cc9-84b2-b29c614c5496: Katello::Errors::Pulp3Error: cursor "_django_curs_140420167436096_227" does not exist

I have no clue how to further debug this. :frowning:
