Hi all, I trying to install the discourse-alt-logo plugin ([https://meta.discourse.org/t/alternative-logos-for-dark-light-themes/88502](https://meta.discourse.org/t/alternative-logos-for-dark-light-themes/88502)), but I’m failing miserably.  
I have already successfully installed several other plugins in my system, this is how my app.yml looks like:

```plaintext
hooks:
  after_code:
    - exec:
        cd: $home/plugins
        cmd:
          - sudo -E -u discourse git clone https://github.com/discourse/docker_manager.git
          - git clone https://github.com/discourse/discourse-voting.git
          - git clone https://github.com/discourse/discourse-solved.git
          - git clone https://github.com/discourse/discourse-canned-replies.git
          - git clone https://github.com/discourse/discourse-alt-logo.git

```

(Note that the topic about installing plugins [Install plugins on a self-hosted site](https://meta.discourse.org/t/install-plugins-in-discourse/19157) has been recently updated with a `"sudo -E -u discourse"` prefix before the git clone command. It’s not clear though if the remaining lines should have sudo as well. But I have tried all combinations: everything wit sudo, everything without sudo, just the first with sudo, etc. What is the correct one?).

Here is part of the rebuild log:

```

However, whatever I do, the plugin doesn’t get installed, no options are displayed, and when I go to the Plugins section in the Admin area, only the previous plugins are listed as installed:

Any ideas?

Alt logo is not a plugin, it is a theme. To install themes follow [How do I install a Theme or Theme Component?](https://meta.discourse.org/t/how-do-i-install-a-theme-or-theme-component/63682)

Silly me. Thanks for pointing out. By the way, what is the correct way to modify the app.yml for plugins? Should I prefix all git clone commands with “sudo”?  
Did you see the “permission denied” in the log above? Could you please enlighten me? Thank you very much in advance.
