The error message mentions:

(for several filesystems (e.g. nfs, cifs) you might need a
/sbin/mount. helper program)

This is relevant given that you are trying to mount NFS. The
/sbin/mount.nfs helper program is provided by nfs-common. You can
install it with:

sudo apt install nfs-common On the other hand, if you are trying to
mount CIFS, the helper program is provided by cifs-utils. You can
install it with:

sudo apt install cifs-utils

最后通过
sudo apt install cifs-utils
