Oracle announced a new maintenance release for VirtualBox 5.2 series a day ago with various bug-fixes.

Changes in VirtualBox 5.2.10 include:

  • VMM: Fixed missing NULL pointer check in MMIO code
  • Storage: fixed having multiple NVMe controllers with ICH9 enabled
  • Network: fixed wireless detection regression when bridging to adapters with unbound IP protocols
  • Network: fixed VERR_INTNET_FLT_IF_NOT_FOUND when bridging to some adapters on Windows hosts
  • Audio: Fixed interrupt storm in FreeBSD guests with HDA
  • Keyboard: Introduced a small delay to fix old software which expects to be able to read an incoming scan code more than once
  • Windows installer: Removed the “Ignore” action in the case the current VBox installation is still running, as the (successful) update will not work until a host reboot is performed
  • NAT: Handle nameserver which is a valid setting
  • BIOS: INT 15h/87h service must disable A20 gate when done
  • Linux Guest Additions: fix a hang starting KDE Plasma

How to Install Virtualbox 5.2.8 in Ubuntu:

1. If you’re still running with VirtualBox 5.1.x, open terminal via Ctrl+Alt+T or from application launcher. Remove old Virtualbox via command:

sudo apt-get remove virtualbox virtualbox-5.1

sudo sh -c 'echo "deb $(lsb_release -sc) contrib" >> /etc/apt/sources.list.d/virtualbox.list'
