Vagrantbox reinstalling the vboxsf driver

The Dragon Boat Festival holiday has been reinstalled Oracle Vagrant Project Medium 21c database , The database can be used , But there is a small warning at the end of the startup process ：

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

Log in to the operating system , Sure enough, I didn't see it /vagrant file system , An error is also reported when executing the command in the prompt ：

$ df

$ ls -lh /sbin/mount.vboxsf
lrwxrwxrwx. 1 root root 49 Jun  4 06:58 /sbin/mount.vboxsf -> /opt/VBoxGuestAdditions-6.1.26/other/mount.vboxsf

$ sudo mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant
/sbin/mount.vboxsf: mounting failed with the error: No such device

Refer to this article ：Vagrant was unable to mount VirtualBox shared folders, Reinstall the driver ：

sudo wget -c http://download.virtualbox.org/virtualbox/6.1.34/VBoxGuestAdditions_6.1.34.iso -O VBoxGuestAdditions_6.1.34.iso
sudo mount VBoxGuestAdditions_6.1.34.iso -o loop /mnt
sudo sh /mnt/VBoxLinuxAdditions.run

The last step takes a long time ：

$ sudo sh /mnt/VBoxLinuxAdditions.run
Verifying archive integrity... All good.
Uncompressing VirtualBox 6.1.34 Guest Additions for Linux........

VirtualBox Guest Additions: Starting.
VirtualBox Guest Additions: Building the VirtualBox Guest Additions kernel

Then the following commands are normal ：

$ sudo mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant
$ df

here vagrant box There is no warning at startup .
