If installing the gvfsd backends again, samba will be the newest version
again. If doing downgrade as you suggested, the backends are gone and I
get the above mentioned error. Isn't there a method how to downgrade the

I know
I did the downgrade also, because since last update I could not
authenticate at windows shares anymore. Now I get following error

file or directory).
any idea?
BTW, in order to be able to access the shares I had to reinstall the
older packages using:
apt-get install samba=2:4.1.6+dfsg-1ubuntu2 samba-common=2:4.1.6+dfsg-
1ubuntu2 samba-libs=2:4.1.6+dfsg-1ubuntu2 samba-common-bin=2:4.1.6+dfsg-
