Ubuntu 18.10 (Cosmic Cuttlefish) has reached end of life, so this bug will not be fixed for that specific release.
** Changed in: linux (Ubuntu Cosmic) Status: Fix Committed => Won't Fix -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1796647 Title: Shared folders cannot be mounted in ubuntu/cosmic64 due to missing vbox modules Status in cloud-images: Fix Released Status in linux package in Ubuntu: Fix Committed Status in linux source package in Cosmic: Won't Fix Bug description: SRU Justification Impact: Vagrant environments are no longer able to use virtualbox feartures like shared folders. This is due to Ubuntu Cosmic kernels currently shipping the upstream vboxguest module and not importing modules from the virtualbox-guest-dkms package. Fix: One solution would be to use the dkms modules for Vagrant, but this is not ideal. At this late stage the simplest solution is to go back to importing the out-of-tree modules. Regression Potential: Minimal. Will have no impact outside of virtualbox environments, and the drivers being imported come from the virtualbox-guest-dkms package in cosmic and are thus expected to work well. --- In bionic, the vboxsf module was included in linux- modules-...-generic: $ dpkg -c linux-modules-4.15.0-36-generic_4.15.0-36.39_amd64.deb | grep vboxsf.ko -rw-r--r-- root/root 63238 2018-09-24 10:08 ./lib/modules/4.15.0-36-generic/kernel/ubuntu/vbox/vboxsf/vboxsf.ko In cosmic, it isn't: $ dpkg -c ~/Downloads/linux- modules-4.18.0-9-generic_4.18.0-9.10_amd64.deb | grep vboxsf.ko This results in shared folders no longer being mountable in Ubuntu Vagrant boxes (and, as the other vbox modules are also missing, probably has other effects that haven't yet been reported). [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.
