Hey Discourse team!

I’m trying to run Discourse Docker on Ubuntu on stable (v2.8.8) and I’m running into the following error:

```plaintext
rake aborted!
NoMethodError: undefined method `min_tags_from_required_group' for #<Category:0x00007fc2ffae9f38>
/src/lib/seed_data/categories.rb:114:in `create_category'

```

### Additional Info of what I’ve done so far:

What I’ve done so far to get here:

```plaintext
sudo -s
git clone -b v2.8.8 https://github.com/discourse/discourse.git
chmod -R 2777 ./discourse
cd discourse

```

I ran into some bookmark issues eariler so I had to:

```plaintext
nano db/migrate/20220104053343_add_bookmark_polymorphic_columns.rb

```

and pasted this: [discourse/db/migrate/20220322024216\_add\_bookmark\_polymorphic\_columns.rb at cd817a436574cd00f0bae339ec0c4fe2fcf2bb50 · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/cd817a436574cd00f0bae339ec0c4fe2fcf2bb50/db/migrate/20220322024216_add_bookmark_polymorphic_columns.rb)

Then when I run:

```plaintext
d/boot_dev -p --init

```

I get the error about min\_tags\_from\_required\_groups.

Can anyone assist?
