1st Post - Linux Upgrade 14.04 --> 16.04 Problems.
Hi all,
My 1st post on here so please be gentle. I am looking for a little help or advice on an issue im having.
I am a real Linux novice but have had a HP Microserver Gen8 with Linux Server on for a while. I run a RAID0 (2 x 3TB) and a boot from a USB. I decided earlier that upgrading from 14.04 --> 16.04 was something i just had to do. <O>
The upgrade all seemed to be fine until it rebooted and then went into Emergency mode. I removed a stale entry from my fstab dir and a few other tweaks and ive managed to get it on at least but it is far from happy.
I did a quick "systemctl status" and got this.

I ran a "systemctl list-unit-files" command and can see the following disabled.
The only thing that has me confused a bit is that you're booting from a USB. I'm not a server type of person, so maybe that is usual.
My thinking is that the install is on a USB stick or drive, and your data is elsewhere?
To me I'd have a boot USB media which contained 14.04 and then an entirely different USB media containing 16.04. If I'm off base with this thinking, then I'd try to roll back to 14.04 and do a full install of 16.04 rather than an upgrade.
Yes i have a USB for the Linux OS and the 2 drives as raid0 for all my data.
The usb had 14.04 on and i have upgraded on the same stick. Your idea of installing on a sperate USB doesnt sound like a bad idea right now! :-)
Are there any decent instructions on roll back anywhere? I have done a quick google and it seems the answer is reinstall rather than go through the heartache of rolling back.

That would be my recommendation too. Sorry, but I feel rollback of any OS is difficult already and really the most experienced people aren't doing a rollback, instead they are recalling a former backup which they performed prior to trying an upgrade.

Indeed. I know the horse is long gone as I bolt the stable door, but for anyone else reading this, it is highly recommended that a user makes a full backup of their system partition(s) before performing an upgrade.
