I still get the issue with the latest version of ubuntu/focal64 (several versions checked: 20210803.0.0, 20210802.1.0, 20210624.0.0):

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,_netdev vagrant /vagrant The error output from the command was: : Invalid argument $ vagrant --version Vagrant 2.2.16 $ pacman -Qi virtualbox | grep Version Version : 6.1.26-1 $ pacman -Qi virtualbox-ext-oracle | grep Version Version : 6.1.26-1 -- 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.
