Hi,

The updated ISOs for the V5.2.0 / V5.2.1 Guest Additions still fails for me on a Debian 9 guest, in the same way as it was previously failing for people on Ubuntu (viewtopic.php?f=3&t=85087, my first post about Debian 9 is the second post in there)

When running the V5.2.0 / V5.2.1 Guest Additions, including both the R118447 and R118452 versions, I don't see any "vboxvideo" module at all in the "lsmod" output. When I back grade to the V5.1.30 Guest Additions, I do see it, and the GAs work correctly.

Attached is a log from VirtualBox with the V5.1.30 and V5.2.1 (R118452) versions installed, but, as the vboxvideo.ko module is not being built and installed, I think any debug information will need to be from the guest additions install process rather than the "outside" log view.

The latest update on the main VirtualBox page, VBoxGuestAdditions_5.2.1-118868.iso, worked for me on Debian 9.2.1 - Cinnamon.

I did run into problems when I tried it on a fresh install of the XFCE version, then I tried a hack-around suggested by twchan in the "vboxvideo build is skipped, Debian 9.2, GA 5.2.1-r118447" thread (sorry, can't post links yet), re-installed the GA iso listed above, restarted, and boom, good to go!

Please try the updated Additions update from today on the Download[1] page. It contains a fix for Debian 9.2 (actually it mostly removes the change which broke it).
