Shared Folder not mounting: unknown filesystem type »vboxsf«

On a Windows 10 host I was using VirtualBox 6.1.6
I had updated my Arch Linux guest system (with Linux 5.5) to VirtualBox GA 6.1.4, because I had read that it would work, but it doesn't work (I can't get the X Window system XFCE started).
So I decided to go back to VirtualBox 6.0.20 on my Windows host.
But after login I get an error message: mount: /home/peter/d: unbekannter Dateisystemtyp »vboxsf«. (unknown filesystem type)
This is what I did in the guest:

Code: Select all

pacman -Rs virtualbox-guest-utils
pacman -Rs virtualbox-guest-modules-arch
cd /var/cache/pacman/pkg
pacman -U virtualbox-guest-modules-arch-6.0.14-9-x86_64.pkg.tar.xz
pacman -U virtualbox-guest-utils-6.0.14-4-x86_64.pkg.tar.xz

In other words: I removed the 6.1.4 guest additions and then installed the last guest additions for the 6.0.x branch from my cache.
Unfortunately I still get the error message that the shared folder is not mounted.

What is wrong?
