I did a test build using a branch of livecd-rootfs where I removed the code installing virtualbox-guest-utils. The vagrant box produced booted fine and mounted guest folders. This works on groovy on the 5.8.0 kernel.
Looking at groovy, vboxsf, vboxguest, and vboxvideo are included as part of the linux-modules package. This was an update done in Focal on 5.4.0-48 and migrated forward. Moving forward for our creation of Vagrant boxes, we can remove the explicit install of vbox-guest-utils. https://packages.ubuntu.com/groovy/amd64/linux- modules-5.8.0-19-generic/filelist -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1895862 Title: vboxsf unable to mount old binary data in Groovy Vagrant box To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1895862/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
