Error updating vom 2.3.1 on 2.3.2 on a katello 3.18.1

Because I want to test Bug #31662: Foreman content proxy doesn't listen on port 80 anymore - Installer - Foreman and 2.3.2 was just released I wanted to update from 2.3.1 to 2.3.2 on my katello 3.18.1 before testing the patch. However, the foreman-installer run quickly failed with an error:

2021-01-20 06:45:50 [ERROR ] [root] Target /var/lib/pulp/media already exists. Unable to migrate Pulp media root from /var/lib/pulp/docroot.

Ensure /var/lib/pulp/docroot is not a directory or /var/lib/pulp/media does not exist.

Both directories exist and both are empty.

Foreman and Proxy versions:
Foreman 2.3.2 updated from 2.3.1
Katello 3.18.1

Distribution and version:
CentOS 7.9.2009

Other relevant data:
During the update the following rpms where updated:

if /var/lib/pulp/media is truly empty, you can remove that directory and re-run the installer.

@ekohl, we wanted to have some guidance for users that run into this situation – did we create any yet?

Just noticed another error message during yum update on the content proxy, i.e. update from foreman 2.3.1 to 2.3.2 on a smart proxy for content on a katello 3.18.1 installation:

Is there any guidance on how to work past this? I ran into this on a test instance today. I can rebuild it if I need to but if there’s an easy workaround I would prefer it.

As mentioned before:

Thanks. That doesn’t apply to my situation. I was asking for the other scenario - if the directory isn’t empty.

Does anybody have any suggestions on how to get past this? I just tested again with 3.18.1 and it’s the same situation.

/var/lib/pulp/media is not empty on this particular system so i can’t use the posted workaround.

What do you have in those two directories?

[root@foremandev docroot]# ls

[root@foremandev media]# ls

And what is inside the artifact directories? The same content?

The directory structures look very similar but I have 49GB in docroot and 8GB in media

I’m pretty sure those numbers correlate to my deb repos in pulp2 (49GB) and my SuSE repos in pulp3. When this instance was built - deb repos were pulp2 only.

In case anybody is in a similar situation and wondering what happened here - I gave up and reloaded it.
