I tried to reproduce this on a simple debian buster system with the
packages from snapshots, via:
apt install /root/wireguard/wireguard{,-dkms,-tools}_0.0.20190702-3_*.deb
modprobe -v wireguard
cat /sys/module/wireguard/version
apt install /root/wireguard/wireguard{,-dkms,-tools}_0.0.20190905-1_*.deb
cat /sys/module/wireguard/version
and that worked as expected.
the equivalent section of the apt output is:
DKMS: install completed.
Setting up wireguard-tools (0.0.20190905-1) ...
Setting up wireguard (0.0.20190905-1) ...
Reloading wireguard module...

I note here that you're not running the latest kernel -- 4.19.0-5-amd64
is not 4.19.0-6-amd64. is it possible that you don't have
linux-image-4.19.0-5-amd64 or its headers installed any more, despite
running that kernel?
Do we need to check that wireguard-dkms specifically succeeded in
generating a module for the running kernel?
i'd have expected that the postinst script itself would verify that
based on its invocation of
modinfo -F version wireguard
which should only verify the available modules for the current version.
can you show the output of:
dpkg -l 'linux-headers-*' 'linux-image-*'
on the affected system?
thanks for the report, and sorry that i'm not currently able to
replicate it, hopefully we can figure it out.
