Hey. Sorry if this is not the right category but I kept going back and forth between this one, support and bugs.

We have a Discourse install that I am trying to upgrade. As in the title, we were going from 2.5.0.beta3 to 2.5.0.beta4. A docker container upgrade was noted (when I attempted the upgrade through the web UI, and then I hit the page “You are running an old version of the Discourse image.” and I need to go the the underling Ubuntu console to run the launcher rebuild app command.

The problem I am running into is this:

```
Launcher is up-to-date
Stopping old container
+ /usr/bin/docker stop -t 10 app
app
cd /pups && git pull && /pups/bin/pups --stdin
/usr/bin/docker: invalid reference format: repository name must be lowercase.
See '/usr/bin/docker run --help'.
cat: cids/app_bootstrap.cid: No such file or directory
"docker rm" requires at least 1 argument.
See 'docker rm --help'.

Usage: docker rm [OPTIONS] CONTAINER [CONTAINER...]

Remove one or more containers
rm: cannot remove ‘cids/app_bootstrap.cid’: No such file or directory
**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one.

```

Discourse-doctor was able to recover the site and get it back up. So that’s good. I am somewhat new to managing our Discourse site and, obviously, need some help to find this. We are running this in a Ubuntu 14.04 Docker container (and, yeah, that needs to be updated to the new LTS soon).

Docker Version is reported as:

```
docker --version
Docker version 17.09.0-ce, build afdb6d4

```

Any help?
