For all new commenters -- what you're experiencing is a new bug with similar symptoms, though slightly different root cause. Note the original bug was "no device found" and this is "Invalid argument."
This appears to be a new bug. I don't see an identical bug to this new issues, so i've opened https://bugs.launchpad.net/cloud- images/+bug/1939580 and copied over comments. Please use issue 1939580 to track this bug -- 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/1873506 Title: ubuntu/focal64 fails to mount Vagrant shared folders Status in cloud-images: Fix Released Status in linux package in Ubuntu: Fix Released Status in linux source package in Eoan: Fix Released Status in linux source package in Focal: Fix Released Bug description: SRU Justification Impact: When our kernel packaging was updated to build the virtualbox guest packages by downloading the dkms package, the modules were accidentally moved to linux-modules-extra instead of linux-modules. This has caused the modules to go missing in our Vagrant images. Fix: Move the modules back to linux-modules. Test Case: Build the kernel packages and confirm that the vboxguest and vboxsf drivers are now in linux-modules rather than linux-modules- extra. Regression Potential: Since linux-modules is required, anyone who is using the vbox drivers will continue to have them after this change. Therefore the risk of regression is extremely low. --- Attempting to `vagrant up` using the `ubuntu/focal64` box fails to mount the `/vagrant` shared folder. `ubuntu/bionic64` works as expected. Here is the Vagrant error message: 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: : No such device To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1873506/+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
