I managed to install umbrelOS 1.1.2 on Ubuntu 22.04 using virt-manager:
1 - Download the usb installation image file and uncompress it
wget https://github.com/getumbrel/umbrel/releases/download/1.1.2/umbrelos-amd64-usb-installer.img.xz
xz -d umbrelos-amd64-usb-installer.img.xz
2 - Run virt-manager and create new VM
Select “Import existing disk image” , select the umbrelos-amd64-usb-installer.img file and choose debian 12 as OS type:
Configure Memory & CPUs. Select “Customize configuration before install”:
On the “Overview” tab, change the default BIOS firmware to “UEFI x86_64: /usr/share/OVMF/OVMF_4M.fd” (and apply):
Last, add some disk (“Add Hardware” on previous image):
Unsolved problem
I managed to boot & install umbrelOS 1.1.2 but… I found some unexpected problem with the dns.
