Black Screen of Death after update to 5.2.6 from 5.2.4

[Dominic M]

I am using Windows 10 to run Oracle Virtual Box 5.2.4. The notification of an update came and I updated it to the latest (5.2.6) and that was fine. I have a virtual machine running Ubuntu 16.04 and while running the old vm tools I updated the vm tools and it crashed. The virtual machine will not boot past the Oracle boot screen

Please try the new GAs from the Downloads page, at the "Important" section at the beginning.

Most probably a duplicate of #17463.

Hello!

I am sorry to inform you but this bug is not resolved with the GA 5.2.7.

My Ubuntu guests sometimes does not start properly and ends up in a black screen, even after updating the guest additions from version 5.6.6 to 5.2.7.

Same issue for me on fedora27 host, my Win10 guest is now broken unless I uninstall the guest additions. Would install 5.2.4 if I knew where to find it.

Try VirtualBox 5.2.8 that just got released...
