Trying to upgrade, but got stuck on this error:
```plaintext

Gem::ConflictError: Unable to activate faraday_middleware-0.11.0, because faraday-1.0.1 conflicts with faraday (>= 0.7.4, < 1.0)
```
I changed `app.yml` to stay on PostgreSQL 10 (I don’t have enough disk space to install 11), so not sure if that’s the reason.

Are you using any 3rd party plugins?

The usual: the bunch of standard `discourse/xxx` plugins plus normal ones like `topic list preview`, `whos online` etc.

I had faraday issue with a 3rd party plugin. I can only suggest try disabling plugins but that probably won’t help here?

Trying with standard upgrade including PostgreSQL to see if it works…
But `pg_upgrade` has been running for a while now… nothing yet…

I suppose the `discourse-azure-blob-storage` plugin is the culprit… again?

That could be the case. I don’t use the plugin so I can’t really comment.

You’ve got conflicting gems because of currently incompatible plugins.
You need to manually resolve that gem dependency in a plugin that is causing this (using version that works with other plugins/core and putting it into plugin.rb) or disable that plugin.

It has been merged.
