Package: virtualbox Version: 4.3.18-dfsg-1 Followup-For: Bug #767201 I got the same problem, I saw that virtualbox now comes with a VNC extension enabled. Disabling it allowed me to access back my VM. So a workaround is to disable this VNC extension.
I tried with 2 VMs, a windows one and a debian (jessie) one. -- System Information: Debian Release: jessie/sid APT prefers testing-proposed-updates APT policy: (900, 'testing-proposed-updates'), (900, 'testing'), (600, 'stable'), (500, 'proposed-updates'), (400, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.16-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages virtualbox depends on: ii adduser 3.113+nmu3 ii dpkg 1.17.13 ii libc6 2.19-12 ii libcurl3 7.38.0-2 ii libgcc1 1:4.9.1-16 ii libgsoap5 2.8.17-1 ii libpng12-0 1.2.50-2 ii libpython2.7 2.7.8-10 ii libsdl1.2debian 1.2.15-10 ii libssl1.0.0 1.0.1j-1 ii libstdc++6 4.9.1-16 ii libvncserver0 0.9.9+dfsg-6+b2 ii libvpx1 1.3.0-3 ii libx11-6 2:1.6.2-3 ii libxcursor1 1:1.1.14-1 ii libxext6 2:1.3.3-1 ii libxml2 2.9.1+dfsg1-4 ii libxmu6 2:1.1.2-1 ii libxt6 1:1.1.4-1 ii python 2.7.8-1 ii python2.7 2.7.8-10 ii zlib1g 1:1.2.8.dfsg-2 Versions of packages virtualbox recommends: ii libgl1-mesa-glx [libgl1] 10.3.1-1 ii libqt4-opengl 4:4.8.6+git64-g5dc8b2b+dfsg-2+b1 ii libqtcore4 4:4.8.6+git64-g5dc8b2b+dfsg-2+b1 ii libqtgui4 4:4.8.6+git64-g5dc8b2b+dfsg-2+b1 ii virtualbox-dkms 4.3.18-dfsg-1 ii virtualbox-qt 4.3.18-dfsg-1 Versions of packages virtualbox suggests: pn vde2 <none> ii virtualbox-guest-additions-iso 4.3.18-1 -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
