That's probably because of the resolution of the virtual package "virtualbox-ose-modules" done by aptitude.
If I remember correctly, there has been a similar bug already been reported before. I'm adding a bug task for aptitude. Have you tested it using apt alone? FYI: $ aptitude search '~Pvirtualbox-ose-modules' p virtualbox-ose-modules-2.6.24-5-386 - virtualbox-ose modules for linux-image-2.6.24-5-386 i virtualbox-ose-modules-2.6.24-5-generic - virtualbox-ose modules for linux-image-2.6.24-5-generic p virtualbox-ose-modules-2.6.24-5-rt - virtualbox-ose modules for linux-image-2.6.24-5-rt p virtualbox-ose-modules-2.6.24-5-server - virtualbox-ose modules for linux-image-2.6.24-5-server p virtualbox-ose-modules-2.6.24-5-virtual - virtualbox-ose modules for linux-image-2.6.24-5-virtual ** Changed in: virtualbox-ose (Ubuntu) Importance: Undecided => High ** Also affects: aptitude (Ubuntu) Importance: Undecided Status: New -- virtualbox installs for the wrong kernel https://bugs.launchpad.net/bugs/188579 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
