I have a similar problem as @bigbrovar regarding the two dual port USB3.0. If I want to attach a 2,5" USB3 disk to the Helios4 I have to use the lower USB port. The upper one "seems" to be dead, but I'm able to connect a thumb drive in parallel at the upper port. I can live with the situation.

I was facing only some minor problems in upgrading OMV4 → OMV5. That's the way to go: https://forum.openmediavault.org/index.php?thread/27909-omv-5-0-finally-out/&postID=219830#post219830 Besides this thread (OMV 5.0 - finally out! :-)) I recommend OMV 5 released! FredK

Release of openmediavault 5 (Usul) https://www.openmediavault.org/?p=2685

I upgraded my Helios4 from OMV4/Armbian4.14 to OMV5 yesterday. After sorting out some minor glitches the system was operable. Today I used armbian-config to switch the kernel to 4.19. Everything seemd o.k. until I tried to inspect my docker containers and I detect a problem with docker-ce which couldn't be started neither re-installed. I had to go back to 4.14. Now I'm rather reluctant to try out one of dev dev-kernels (5.4.x). Any clue? Edit: as proposed by Koen solved the docker problem.
