VirtualBox 6.0.10 Adds UEFI Secure Boot Driver Signing Support on Ubuntu and Debian

VirtualBox 6.0.10 comes more than two months after the previous maintenance release with some notable changes for Linux-based operating systems, especially Ubuntu and Debian GNU/Linux hosts, which received support for UEFI Secure Boot driver signing. Additionally, Linux hosts got better support for various kernels on Debian GNU/Linux and Fedora systems. It also fixes focus grabbing issues reported by users when building VirtualBox from sources using recent versions of the Qt application framework. The Linux guests support was improved as well in this release with fixes for udev rules for guest kernel modules, which now take effect in time, and the ability to remember the guest screen size after a guest reboot.
