Error: 'ensure smbclient is in the path or php-smbclient is installed'

I just installed NC 19.0.0 on VM in my home server. (Ubuntu server 20.04)
My home server is Windows, and have network drives, since that I’m using external storage with smbclient.
It working very slow, in my local network also, so I check the logs and I see a lot of this massage:

OCP\Files\StorageNotAvailableException: No valid backend available, ensure smbclient is in the path or php-smbclient is installed

The smb is working, but always got this error, and from mobile it’s crash sometimes.
Maybe someone know how to improve that or fix this error?
