Wrong, the update without systemd already has broken Virtualbox. By accident I sent the wrong, unedited mail. That I need this old version of Virtualbox (4.3.12-1) soon or later might become a serious issue, however the culprit is libvpx. Downgrading libvpx (1.4.0-2 -> 1.3.0-1) ffmpeg (1:2.6.2-1 -> 1:2.6.1-3) ffmpeg-compat (1:0.10.16-1 -> 1:0.10.15-2) solved the issue and keeping systemd up to date doesn't cause an issue. OT: "downgrade Description: Bash script for downgrading one or more packages to a version in your cache or the A.R.M." Unfortunately A.R.M. is missing a lot of packages. Regards, Ralf
