NV41 heads Qubes 4.3 upgrade

Hello!

I tried several times to upgrade to Qubes 4.3 from 4.2, both in-place and via USB (both dd and etcher made Installation USB device). The in-place update stopped “unexpected issue” and for the installation device method the usb-device is never found.

Could it be a problem caused by the BIOS version? Currently i run on Heads 2.4.1.

Other rumoers that i heard to make upgrades finish successfully :

  • remove older templates and vms
  • On non heads devices: disable secure boot/bios security chip

Does anyone have any idea? I would be happy to hear your experiences.
