Thanks for all the support, unfortunately it does not solve the problem.

For new users maybe worth to add a:

1. enter container (e.g., `./launcher enter app`

So I did. And `pnp` was already installed:

```plaintext
root@vtdiscourse-app:/var/www/discourse# pnpm --version
9.5.0

```

I already did, as written in my post above, without solving the problem.

Discourse was installed in _April 2023_.  
I did upgrade successfully up (and including) to _v3.4.0.beta3_.  
As written above, the OS is a LXC container, using _Debian bullseye with latest updates installed_.

The only installed extension is the [Private Topics Plugin](https://meta.discourse.org/t/private-topics-plugin/268646) (still under maintenance and also kept up to date with each discourse update on my side).

          - git clone https://github.com/communiteq/discourse-private-topics.git

## Any custom commands to run after building
run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

```

Any help appreciated.
