Please see the following error that I seem not to be able to get past
ERROR: failed to solve: process “/dev/.buildkit_qemu_emulator /bin/sh -c apt-get install -y git python3 build-essential” did not complete successfully: exit code: 100
do you try to install umbrel on an emulator?
i would suggest to use at least a virtual machine from ubuntu/linux to get run properly.
even every linux or debian based os is fine.
maybe the issue comes because you try to use an emulator.
cheers
