I *have* built the template and do not have this problem.
Are you sure that is your issue?
If so, there's clearly something majorly wrong with your arch building
environment.
I suggest you clean it out, and start again.
1. Run ./setup and make sure that only arch is selected.
2. Run `make clean-rpms`
3. Confirm that chroot-vm-archlinux is not present.
Delete (using sudo) if it is.
4. Confirm that
qubes-src/linux-template-builder/prepared_images/archlinux.img is not
present.
Delete (using sudo) if it is.
5. `make qubes-vm` and `make template`
Alternatively I provide pre-built templates, and Arch packages at
https://qubes.3isec.org
Download an arch template, confirm the signature, copy it in to dom0 and
install it using `dnf install`
