After the last kernel upgrade in Ubuntu 12.10 I had to manually re-load two kernel modules for Virtualbox.
modprobe vboxdrv
and modprobe vboxnetflt
I don't know enough about the system to say if this is a bug, or if it's supposed to be like that, but it is rather inconvenient. As a user new to Ubuntu, it was fairly time consuming to find out what had to be done.
It was an automatic update, which asked me to reboot when it finished. After re-boot, virtual machines wouldn't run until I had re-loaded the modules.
So my questions are: is this normal? Will it happen with other packages, or just Virtualbox? Is the updater supposed to do this automatically? Should I file a bug report, and if so, to whom?
