Hello. I’ve been trying to migrate our current Discourse server and am trying to do a fresh install on our new VPS, but using our App config bootstrap was failing with a weird error.  
I tried bootstrapping from scratch with the `./discourse-setup` script but even that was failing. Was wondering if there are any issues with the script at the moment?  
Error seen below:

This happens when the server doesn’t have enough memory. How much RAM and/or SWAP this server have?

Total of 4G with about ~2.5G free when I run the launcher

```plaintext
total used free shared buff/cache available
Mem: 3911 715 2773 1 683 3196
Swap: 0 0 0

```

No swap though since I thought it wasn’t necessary on systems with \>2GB available. I’ll try adding a swap partition.

Thanks for reporting the result, I’ve made a change for that to happen automatically
