[SOLVED] Mounting shared folders in the VirtualBox guest. solved

After updating the system, shared folders were no longer mounted in the guest system. When I mount it manually I get:

mount -t vboxsf backup /backup
mount: /backup: mount(2) system call failed: Protocol error.
dmesg(1) may have more information after failed mount system call.

After checking, it turned out that the mount.vboxsf executable file disappeared from the system

Does anyone know what happened to VirtualBox again?

Re: [SOLVED] Mounting shared folders in the VirtualBox guest. solved

I don’t understand after what actions it started mounting, but manual mounting mount -t vboxsf data / data started working without a single virtualbox package in the system and without the mount.vboxsf executable file (it is no longer needed).
to automatically mount without prescribing in fstab, it is enough to install virtualbox-guest-utils-nox or virtualbox-guest-utils and systemctl enable vboxservice
