migrate sqlite3.OperationalError

Issue summary

Having a fresh wagtail installation, I'm getting an error when trying to execute python manage.py migrate

models.py:

from django.db import models

from wagtailtrans.models import TranslatablePage


class HomePage(TranslatablePage):
    pass

generated migration:

# Generated by Django 3.0.8 on 2020-07-14 17:47

from django.db import migrations, models
import django.db.models.deletion


class Migration(migrations.Migration):

    dependencies = [
        ('wagtailtrans', '0009_create_initial_language'),
        ('home', '0002_create_homepage'),
    ]

    operations = [
        migrations.RemoveField(
            model_name='homepage',
            name='page_ptr',
        ),
        migrations.AddField(
            model_name='homepage',
            name='translatablepage_ptr',
            field=models.OneToOneField(auto_created=True, on_delete=django.db.models.deletion.CASCADE, parent_link=True, primary_key=True, serialize=False, to='wagtailtrans.TranslatablePage'),
            preserve_default=False,
        ),
    ]

How to reproduce?

After installing wagtail (Following all the steps here https://docs.wagtail.io/en/v2.9.2/getting_started/tutorial.html just before Extend the HomePage model), proceed to install wagtailtrans following the steps here https://wagtailtrans.readthedocs.io/en/latest/getting_started.html

Try to run

$ python manage.py makemigrations
