+1 for keeping Unity8 as a name.
Besides the massive effort in promoting the name by Canonical, it will always be based on the Unity8 source code, provided by Canonical. If it gets rewritten from the base up, its not Unity8 anymore. Same applies to Unity7 imho.
just my cents 
After a few crashes, when opening Dolphin, which dropped me back to a not responding TTY and some reboots, I got it running!
Thing is, I use a Lenovo Twist, which apparently doesn't have a recognized/working screen-rotation-detection and there is no manual way of rotating the screen like in unity7, which I am using right now. Unity7 is just not geared enough towards tablet-style-usage, but will have to do
how does the actual development process of Unity8 go? (If there is a development process)
How many people are contributing, what is being worked on, I would love to get some insights 
Greetings and good luck,
I am staying connected
Thanks for the quick reply!
I ll stick around and wait till it works
Hey guys
I'm constantly checking back here, to see if I can go for unity8 on my 18.04 machine yet.
Could you please give me an update on if it's apt install unity8 and everything is running to try it out, our would it still need a lot of commandline-work?
greetings
Walter
