Hi there, I ran an upgrade on my DigitalOcean droplet for Discourse and have this error, it appears to have hung in the console. Anyone know what I should do? Bounce machine?

Bounce machine and run another rebuild sounds like a good idea. Also be sure to have swap set.

OK bounced server, logged in as root and it shows this when I try to rebuild. Am I doing something wrong?

You are missing a `cd` there … try.

```plaintext
cd /var/discourse
./launcher rebuild app

```
