I am trying to setup one of my servers with Ubuntu 18.04 server edition. When trying to do disk partitioning it does not allow me to choose Software RAID configuration (That open does not exist at all). How can I solve this.

Note: I tried with Ubuntu 16.04 and it works fine

  • What commands did you use as I have created it on a virtualbox instance of Ubuntu Bionic? – George Udosen Apr 29 '18 at 20:23

You're downloading the wrong version. Ubuntu 18.04 has a "live server" version which has a faster/easier, but less configurable installer.

You want to download the alternative installer instead: http://cdimage.ubuntu.com/ubuntu/releases/bionic/release/

  • This is a really interesting issue... I like the idea of a streamlined installer, but sometimes you need to configure things. Thanks! – Snappawapa May 3 '18 at 23:18

Going crazy with this problem where the gory details are on Usenet alt.os.linux at URL: https://groups.google.com/forum/#!topic/alt.os.linux/D7E7FQ1NLNk

Why doesn't Ubuntu 18.04 ask to install next to Windows 10 Pro single HDD as a dual boot?

Basically, Ubuntu 16.04 works fine but Ubuntu 18.04 installer fails every time: https://www.ubuntu.com/download/desktop

Some debugging commands that others will find useful and their output are:

blkid /dev/sd*

  /dev/sda: TYPE="promise_fasttrack_raid_member" <===== this is critical data!!!

  /dev/sda1: LABEL="Disk1" ... TYPE="ntfs" ... 

sudo fdisk -luS /dev/sd?

sudo apt install smartmontools

When it asks for a mail-server configuration, I selected:

   No configuration

Then I could run the smartctl command:

sudo smartctl -A /dev/sda

Power_On_Hours = 208 (Raw Value)

(The point is that it's a new HDD and I didn't get cheated with an old one!)

The net is that there is a huge bug in omission in the description for the Ubuntu 64-bit Desktop 18.04 installer which works DIFFERENTLY from the 64-bit Ubuntu Desktop 16.04 installer in the exact same machine under the exact same circumstances.

The Ubuntu 16.04 Desktop installer installs alongside Windows when the controller is RAID but the disks are not RAIDed; but the Ubuntu 18.04 Desktop installer not only barfs but it provides zero useful output under the exact same circumstances.

This bug is evident in the tutorials also in that they don't cover this situation in the least, so everyone is left to fumble willy nilly until they figure out, on their own, with no help from Ubuntu, about this bug.
