Microstack installs STEIN version, not USSURI

[Monty McGraw]

I installed Microstack on a PC running ubuntu 20.04 today (Feb 22, 2022) and got USSURI version.

sudo snap install microstack --beta --devmode

snap list microstack
Name Version Rev Tracking Publisher Notes
microstack ussuri 241 latest/beta canonical✓ devmode

I also installed Microstack on an NVIDIA BlueField-2 running ubuntu 20.04 today and got STEIN version.

I couldn't use --devmode on install the error message said to use --classic.

sudo snap install microstack --beta --classic

snap list microstack
Name Version Rev Tracking Publisher Notes
microstack stein 199 latest/beta canonical✓ classic

I'm concerned about using the two different versions.

Why doesn't ussuri get installed on the aarch64 BlueField-2?
