Setting up a server on an Ubuntu 16.04 VM

[Bradyhawke]

Hey guys,

I'm looking to set up a server for experimentation on a VM running Ubuntu 16.04, and I keep coming across some issues. Before I go all into the issues though, I figured I should check and see if there is a recommendation as to a different flavor / version of Linux / Ubuntu over 16.04?

Thanks!

I'm attempting to install a server on an Ubuntu 16.04 VM - the VM stats:

• 100GB HDD space
• 16GB Memory
• 4 x CPUs (1 core per socket)

I'm using the Linux installation found here:

https://github.com/EQEmu/Server#-deb...tucentosfedora

The installation begins just fine, but then it locks up after a few warnings during the "Building EQEmu server code" process - see code below:

It gets to that point and the VM stops responding. Any help or suggestions as to what is going wrong would be greatly appreciated.

Thanks again!

I just did this on a new test server using Debian 9, which is what ubuntu is based on and it worked perfectly. At the point you are seeing those warnings, the terminal acts like it has locked up, but it has not. The server is actually building, compiling, etc. You need to be patient and wait. I'm talking like 30+ minutes depending on your computer's capabilities, how much resources you gave the VM, etc.
