I was able to install Qubes without any modifications using Qubes-20210814-kernel-latest-x86_64.iso 14-Aug-2021 05:54 5795479552
The most recent releases of Qubes OS are here: Index of /qubes/iso/
But I was unable to start OS though.
I know, there are some newer builds, but since 4.1 Qubes installs before HW checks and it takes the hell more time to test. Moreover, it does not update during installation like linuxes generally do. And that could help a little.
So, I’ve decided to install Kubuntu 20.04.2 LTS to try. It was interesting because I’ve got two errors that may explain the problem.
First try The latest stable build of Kubuntu did not start.
Error1: AMD-Vi - IOMMU
Error2: certificate X.509
Second try The same installer, but with update in the installer.
Error: certificate X.509
System did not boot. I tried [recovery mode] and the system started with the same
Error: certificate X.509
So, after logged to the system in recovery mode I started updater and there was endless list of updates, including kernel-firmware, and my laptop now works almost perfectly.
The only issue that it does not go to sleep with display closed, I have to choose the option from menu and only then I close it. Not a huge problem to activate sleep through menu, but you should know this.
The most working OS for 5800H is Fedora. People report that it installs without any issues. But I prefer Debian, and today I fell in love with KDE It’s so amazing that I want to leave my laptop and will install Qubes after it goes stable with 5800H support.
PS: I dream of having KDE as default in Qubes setup. It looks professional and runs almost perfectly (had to tune it for 4K display).
