Server’s RAID died couple days back and we’re trying to bring back to life our Discourse instance from a filesystem backup. No luck so far.

I get this error message from `./launcher rebuild app`:

```plaintext
FAILED
--------------------
Pups::ExecError: /root/upgrade_postgres failed with return #<Process::Status: pid 46 exit 1>
Location of failure: /pups/lib/pups/exec_command.rb:112:in `spawn'
exec failed with the params "/root/upgrade_postgres"

```

Its output claims that I should be able to just `./launcher start app`, but it fails with:

```plaintext

docker: Error response from daemon: pull access denied for local_discourse/app, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

```

[Full output of both commands available here](https://gist.github.com/ulysses4ever/35e8683dfc39358c20f6d2e2309ca79e).

Just in case, my `docker ps` is empty.

I’m not sure how to proceed and will appreciate any help.
