Odroid with Ubuntu

Hi all,
I am trying to run Umbrel on an Odroid XU4 running Ubuntu 20.04.
It seems that the installation (including Docker) has gone ok so far, but now I run the start script and nothing seems to happen. I can’t connect to http://umbrel.local and I can’t ping it either.
Is there anyone here who can help me out please?
Many thanks!

when you can‘t reach and can’t ping it‘s not working properly.
maybe reinstall it that helped me put when i installed on ubuntu and it was not working the first attempt.

you can also check if you can find the home/umbrel directory
