VM's based on archlinux/blackarch not working for me too.
Any application started on Archlinux template has been blocked :
Arch Linux 4.4.38-11.pvops.qubes.X86_64 (hcv0)
archlinux login : [ 10.052051] audit_printk_skb: 39 callbacks suppressed
[ 10.052073] audit: type=1006 audit (1484564681.373:14) pid=624 uid=0 old-auid=4294967295 auid=0 old-ses=4294967295 ses=8 res=1
Archlinux template cannot be remove in Qubes manager, only manually.
By default fresh archlinux template install :
archlinux% pacman -Q xorg-server
xorg-server 1.18.4-1
When upgrade system :
:: qubes-vm-qui: installing xorg-server (1.19.1-1) break dependency 'xorg-server<1.19.0'
Trying remove xorg-server, then Suuy/Suy, then install xorg-server from AUR. It works until the first template shutdown start.
