Cannot update dom0, fedora-26 botched

[bb...@disroot.org]

This all happened after a fresh install of RC4 (4.0 stable installer will not boot on my hardware) where no Fedora-based VMs or fedora-26 itself would launch anything. All qvm-run's just hanged, and logs only report after killing a VM:
``libvchan_is_eof
Icon size: 128x128
domain dead
Failed to connect to gui-agent``

I tried reinstalling the template and here we are. Cannot update with any repository enabled, disabled. I have changed all mirrorlists from https to http and back.
After going through hundreds of packages like this, it gives the output:

Try running "qubes-hcl-report" and look for the 5 lines at the end about
HVM, IOMMU, etc. Does "qvm-ls" show any running VMs? Can you start a
console session in any of them? Debian template based AppVMs work better?
If so, try changing your UpdateVM to a Debian based one then updating all
your templates and dom0.
