This worked fine on 17.04:
sudo mount -v -t cifs -o username=myname,password=mypassword //nas/share /mnt/nas
Now on 17.10 it gives me:
mount.cifs kernel mount options: ip=192.168.1.150,unc=\\nas\share,user=myname,pass=******** mount error(95): Operation not supported Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
A singularly unhelpful error message, given that the manpage hasn't changed. I can't figure out how to increase the verbosity of the error message beyond the above. How do I persuade mount.cifs to tell me what it doesn't like?
