Got same issue when upgrading to virtualbox 5 on Ubuntu 16.04. Fix was to uninstall & purge all old virtualbox packages:
# Find your installed old packages with: sudo dpkg -l | grep virtualbox # Uninstall all packages listed: sudo apt-get purge virtualbox-qt virtualbox virtualbox-dkms virtualbox-4.2 virtualbox-4.3 unity-scope-virtualbox sudo apt-get autoremove Then, try re-installing the new virtualbox: sudo apt-get update && sudo apt-get install virtualbox I was using oracle deb repo packages, but should work for others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1608208 Title: package virtualbox 5.0.24-dfsg-0ubuntu1.16.04.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/virtualbox/+bug/1608208/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
