Thanks for sharing your experience with UT!
I also had a hard time in the beginning. It took me and a friend alone 3 days to install it.
With windows 10 we desperately failed.
To wait one week, before Xaomi opened the boot loader, it made things not easier.
On Linux Mint than we succeed.
With the community I made the same experience like you: they are very supportive.
After they told me about waydroid, things went easier. It made it possible, to use it as my daily smartphone.
I love the idea of a open source system, what is build neither on android nor iOS.
This is my motivation, to go thru the challenges and stay on UT.
My impression is, that there is a lot of potential with in the community and the developers.
I think, more sooner than later UT it will grow exponential.
In the last Q&A (176) Marius said, he will build a group, that sort out, how to optimize UT for the normal user.
I am confidant this will bring the system way more forward, in terms of usability.
