So, at first Samba worked even after the update, Due to lack of GB on server side hard drive i changed the label of a drive. altered all i needed to relevant places and files. All worked, could acces from windows laptop and linux laptop.
After a couple of days i noticed drives were not mounted on my linux laptop. thinked not to much of it yet. My wife complaints that the server is unreachable and now after investigating i ran out of options :
tail -f /var/log/kernel.log
gave the following in the beginning :
Oct 15 21:43:07 Laptop kernel: [ 3910.412985] 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.
Oct 15 21:43:07 Laptop kernel: [ 3910.418005] CIFS VFS: Error connecting to socket. Aborting operation.
Oct 15 21:43:07 Laptop kernel: [ 3910.418016] CIFS VFS: cifs_mount failed w/return code = -111
so i changed /etc/fstab entry and added :
/media/movies cifs auto,*`vers=1.0`*,credentials=/etc/samba/user,noexec 0 0
which only left me with :
Oct 15 21:49:06 Laptop kernel: [ 4269.887208] CIFS VFS: Error connecting to socket. Aborting operation.
Oct 15 21:49:06 Laptop kernel: [ 4269.887218] CIFS VFS: cifs_mount failed w/return code = -111
So i got the version right, but now it leaves me with return code -111 which google says basicly anything can be wrong.

probably everybody notices the obvious, but my knowledge is not that great, so i hope people here know some other solutions or maybe give me pointers as i think this goes beyond novice level :)
Maybe the best advise is to copy /etc/samba/smb.conf and re install samba. or run an alternative (is there any?)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 16-10-2018 added:
looks more and more that the server side isn't available : when using
sudo smbclient -L //server_ip -U user
i get prompted for user password which after i am certain i added the correct password :
WARNING: The "syslog" option is deprecated
Enter diet's password:
Connection to 192.168.178.21 failed (Error NT_STATUS_CONNECTION_REFUSED)
Added more :
When command nmblookup is performed on client side, the server does not show, tried various variations of the command, but the servers ip address did not show. smbtree also gives no server.

Google Led me to bugzilla where i find "exactly" the same fault codes.
Now is the question, how do i get this solved? how do i downgrade to libtevent 0.9.28 to see if this gets it fixed?
i found this page so i know it is in older repositories, which i added but when i use
diet@rabbithole:~$ sudo apt-get install libtevent-dev=0.9.28-0ubuntu0.14.04.1
i get
Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:
The following packages have unmet dependencies:
libtevent-dev : Depends: libtevent0 (= 0.9.28-0ubuntu0.14.04.1) but 0.9.34-1 is to be installed
E: Unable to correct problems, you have held broken packages.
Although i think i am on to something, i am wondering why i am having this issue after updating to 18.04. the buzilla report dates from a while back with solutions mentioned that i cannot roll out yet because off my lack of skills to do a rollback on a package and its dependencies.
Well, I got it solved by rolling back libtevent to 0.9.28
commands used :
First i added the following repository to /etc/apt.sources.list :
then did
now you can do 2 options where option 2 gives less output
option 1
option 2
you will see that older versions will be available
next
press y and enter
and the roll back is a fact.
for safety i marked the libtevent package not to be updated anymore. not sure yet what the consequences will be in the future.
Hope this will help others whom may encounter the same issue as i did.
