My understanding of the issue after an IRC conversation with sforshee is that the modules were intentionally dropped from the kernel packages, but the corresponding Provides of virtualbox-guest-modules was _not_ dropped from the kernel packaging. This means that when we install virtualbox-guest-utils during image build, it sees the modules as already available so does nothing. (Instead, it should have to fulfil the dependency some other way, probably by installing the DKMS packages which build the drivers).

[Original Report] Just tried to test out the new cosmic64 vagrant box and get the following error; ``` Vagrant was unable to mount VirtualBox shared folders. This is usually because the filesystem "vboxsf" is not available. This filesystem is made available via the VirtualBox Guest Additions and kernel module. Please verify that these guest additions are properly installed in the guest. This is not a bug in Vagrant and is usually caused by a faulty Vagrant box. For context, the command attempted was: mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant The error output from the command was: /sbin/mount.vboxsf: mounting failed with the error: No such device ``` I tried with ubuntu/bionic64 and it worked fine. I've got; $ vagrant version Installed Version: 2.1.5 Latest Version: 2.1.5 You're running an up-to-date version of Vagrant! $ VBoxManage --version 5.2.18r124319 $ To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1796647/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
