I have same situation installed ubuntu has bad partition table or huge list of stupid package installed. Datacenter network is my primary concern or it's really cheap price but administrators dosn't care. What should i do? That's my way to solve this issue easily.

Ask them to install ubuntu server what ever is it. re install it over ssh, repartition and get clean installation of ubuntu server.
Create your own netiso and reinstall it over ssh. You can partion yor server as you desire. And set more configuration using [ubuntu preseed](https://help.ubuntu.com/lts/installation-guide/armhf/apbs02.html) just over ssh; no kvm/ipmi/vnc required.
### Requirement
It's simple, create modified iso based on your network and preseed url file and continue installation over ssh.
I use mini.iso because it's small and get most packages from ubuntu repository so you server after installation is fully updated.
### :warning: Requirement
1. Installed ubuntu version on server via ssh access
2. Clone this repo to your server
3. Copy `config.sample` to `config` file and edit field by field exactly:
2. Root access require (or sudo user).
