Requisites

• A manjaro x86_64 VM with X (see https://gitlab.manjaro.org/man...jaro-arm-installer/-/issues/10 4 for the reason behind the X requirement)
• An extra disk. In my case, I've used a 8gb qcow2 empty file mapped as sata (important as the script only recognizes /dev/sd* or /dev/mmclblk* devices) so it is /dev/sda in the VM.

Process

• ssh into the VM
• pacman -Syyu manjaro-arm-installer
• Reboot (just in case as it should have updated a few packages, including the kernel)
