cifs mount error(2): No such file or directory

I have a Buffalo Neworkstorage (NS) installed. I am able to mount the NS from my Rock Pi N10 running Debian (buster) using the following command: sudo mount.cifs //>/SHARE /mnt/lspro But on my PC running Ubuntu 18.04, using the exactly the same command as above, I got an error: mount error(2): No such file or directory Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) The dmesg logs are: [48381.426142] CIFS: Attempting to mount //10.1.10.77/share [48381.426168] No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount. [48381.440240] CIFS VFS: cifs_mount failed w/return code = -2 /mnt/lspro exists on the Ubuntu box. I can cd /mnt/lspro and ls /mnt/lspro it's confirmed it there! I can even mount the NS through Files other location by "smb://" using Anonymous without password, but I cannot mount.cifs in the Ubuntu box. Does anyone have the same situation and found a solution?
