Upgrade to OMV3 from 2 missing GUI, tried to uninstall/reinstall

Upgraded from 2 which looked successful, but I couldn't get any response from GUI. I troubleshot various "cures", but finally decided I should have uninstalled all the plugins before the update. I then CLI to uninstall plugins and then uninstalled OMV. I ran:

apt-get install openmediavault

It looks like the path to get the OMV files is wrong, but I can't seem find a fix. I hope I haven't totally bolluxed this up, but as a noob, I'm stuck.

Thanks in advance.

Two things
1) sorry I posted this in the "Announcements" section, I was aiming for Installations: Updates/Upgrades. I don't see a way to move it so I'll assume one of the moderators can put it in the right spot.
2) I found ryecoaaron's post Guide to install on Deb 8.x Jessie? and tried his instructions. After executing apt-get install openmediavault:

Thanks, Your are correct except that I didn't actually "chose" the location, but I did recognize it wasn't the right spot, but don't know how to move it. Moderators?

Hi,
Still playing around with 3.0, but haven't gotten it installed/running properly. I keep getting "MDADM.CONF defines no arrays" and when I try to log on to the GUI I get Error Message and here's the details:
Error #0:exception 'OMV\Rpc\Exception' with message 'Failed to connect to socket: No such file or directory' in /usr/share/php/openmediavault/rpc/rpc.inc:138
Stack trace:

Help or clues to go from here would be gratefully accepted.

Thank you Ryecoaaron. Before i saw your response, I decided to burn a 3.0 beta ISO and do a fresh install (note, I had upgraded from 2 previously). On boot, I got mdadm messages I logged into GUI and set up new OMV which seems to be working. I ran your instructions above via SSH,

mdadm --examine --scan >> /etc//mdadm.conf
mdadmupdate-initramfs -u

I get (BTW I've never set up any RAID):
W: mdadm: /etc/mdadm/mdadm.conf defines no arrays.
W: mdadm: no arrays defined in configuration file.

cat /etc/mdadm/mdadm.conf

Yields:

# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#
# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.
# Note, if no DEVICE line is present, then "DEVICE partitions" is assumed.
# To avoid the auto-assembly of RAID devices a pattern that CAN'T match is
# used if no RAID devices are configured.
DEVICE partitions
# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes
# automatically tag new arrays as belonging to the local system
HOMEHOST <system>
# definitions of existing MD arrays

I rebooted the system and see message (via journalclt -b):

mdadm-raid[221]: Assembling MD arrays...done (no arrays found in config file or automatically).

Should I update Grub too?

cat /proc/mdstat

Personalities :
unused devices: <none>

I've never set up RAID on this machine.

That's kinda what I thought, but I'm not really sure why its thinks it should.
