So you tried x86 version[1]? The guide for x86 is still rough.
Yes, I was trying in a test VM and bare build. To be fair I also could not get umbrel to run with any form of stability either.
I am fairly good with linux, but these 'nodes in a box' really seem (or in the case of umbrel seemed, the just did a lot of work with the x86 have not tested) to be built around the RPi world and x86 is a afterthought. Even mynode which has a PREBUILT VM image that you can download seems to have more issues with that version then their SBC based ones. [at least if you read their forums]
From yesterday browsing, i only found the warning once at their OS repository[2].

[2] https://github.com/runcitadel/os#%EF%B8%8F-dont-be-too-reckless
Such warning
It's not just the fact that it's there once. It's at the bottom instead of the top. And it's saying that things may break. NOT that it's insecure which umbrel fully admits to.
Could just be it's still early on and they are tweaking things including code comments and so on.
