I will upload my builds and write under what os compiled.
Universe(uni) - https://github.com/universe-project/universe/releases/download/v2.0.0/universe-qt-raspberry.zip (Raspbian Strech 2019-04-08)
I'm sorry to ask and this may be even beside the point of the topic but is UNI worthy enough to spend my time to deploy your wallet on Raspberry Pi? That's more about what I didn't get i.e. the value of UNI atm, transactions seem to be going trough network but the price is zero and I'm a little confused with that.
Now the network was fork. And the pos was cut from 100% per year to 10%. And every year it will be less. In three years it will be equal to 1% per year. So I hope that the course will go up. The project team is working and rolling out new projects. For example World of Warcraft with cryptocurrency: http://uniwow.ru
