Device: rock64v2
OS: Armbian Ubuntu Bionic Desktop 5.90 via the pine installer
Installation steps: flash drive, install in rock64, turn on, run sudo apt-get and upgrade, reboot.
Install snap. reboot. All is fine.
Install hello-world (or any snap as far as I can tell), and reboot sets off an endless recursive reboot cycle. I can’t give logs because, as I said, endless reboot cycle.
Eventually I managed to get back into the OS after many reboots. I immediately removed snap. OS reboots perfectly fine.
