I have the same issue. I thought there weren't any new updates, but it's been like this for a while.
There are two updates listed, but they never get installed. Note: I am not using the regular sys-net as my updatevm (I am using a plain fedora 29 VM, that is connected to sys-firewall, which is connected to the sys-ethernet VM to which the PCI device is attached). Log: Using XXX as UpdateVM to download updates for Dom0; this may take some time...
