Error in update of package qubes-kernel-vm-support.x86_64 4.0.20-1.fc28

[Steve Coleman]

After a normal dnf update this error was displayed, because the old
package is not erasing correctly. building the u2mfn from source did not
help.

Looks like u2mfn is only in the debug version of qubes-libvchan-xen?

dnf install of qubes-libvchan-xen-debugsource does not help

Looks like some previous update failed to remove 4.0.19-1.fc28 version
and now you have both.

Probably qubes-kernel-vm-support-4.0.19-1.fc28.x86_64 was half-removed
already. Cleanup it with bypassing scripts:

sudo rpm -e --noscripts qubes-kernel-vm-support-4.0.19-1.fc28.x86_64
