Trying to migrate my installation (https://9854.moe) to a external server and it will not build or compete the setup. It always gets stuck here

Welcome to NodeBB v1.7.5!

This looks like a new installation, so you'll have to answer a few questions about your environment before we can proceed.

Killed

I dont know where "Killed" is coming from but i have tried making a whole new install and same result

How much memory does your server have? Do you have swap setup?

[kazari]

@baris 512 MB and no swap. The server is from Vultr
My current server is 512 MB with 512 MB Swap. That server is a VMware VM on my ESXi Server

[baris]

Try setting some swap, the build process can consume more than 512mb memory and that would cause the process to be killed.

@baris That seems to have solved it, Thanks a lot.
