I just got the scanner from Samsung M2070FW running with Ubuntu 18.04. Just follow these steps:

1. 
   

   Get UnifiedLinuxDriver-1.00.37.tar.gz from this site and unpack it, open a terminal and do:

   
   
   

   cd /UnifiedLinuxDriver-1.00.37/uld
   
   sudo ./install.sh
   
   

   
   


2. 
   

   After successful installation of the Samsung Driver for the printer and the scanner, you can installer the printer first via Cups. For the scanner however, there should be a new directory with a single file in it:

   
   
   

   /opt/smfp-common/scanner/lib/libsane-smfp.so.1.0.1
   
   

   
   


3. 
   

   If you use a 64-bit system (which you probably do), use the terminal again to change to the scanner driver directory. Here you put a symbolic link to the file in /opt:

   
   
   

   cd /usr/lib/x86_64-linux-gnu/sane
   
   sudo ln -s /opt/smfp-common/scanner/lib/libsane-smfp.so.1.0.1 /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1
   
   

   
   


4. 
   

   But things still didn't work, so I had to install a USB library:

   
   
   

   sudo apt install libusb-0.1-4
   
   

   
   
   

   After that, I made sure that I was in the same network with my printer (via ping) and did scanimage -L:

   
   
   

   $ scanimage -L
   
   device `smfp:net;192.168.1.20' is a Samsung M2070 Series on 192.168.1.20 Scanner
   
   

   
   


5. 
   

   If pinging your scanner works but the command finds nothing, you can start to debug things:

   
   
   

   cd
   
   export SANE_DEBUG_DLL=255 && scanimage -L &> debug.txt
   
   grep -n2 "libsane-smf" debug.txt
   
   

   
   
   

   If everything works correctly, you would get the following output:

   
   
   

   ....
   
   84-[dll] sane_get_devices
   
   85-[dll] load: searching backend `smfp' in `/usr/lib/x86_64-linux-gnu/sane'
   
   86:[dll] load: trying to load `/usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1'
   
   87:[dll] load: dlopen()ing `/usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1'
   
   88-[dll] init: initializing backend `smfp'
   
   89-[dll] init: backend `smfp' is version 1.0.1
   
   ....
   
   

   
   
   

   If not, you might find a hint as to what file is missing or not found.

   
   

See the bug report of this problem and the workaround that I posted in that bug report. Let me sum it up here to help you out:

1. 
   

   Link the files libsane-smfp* in the sane folder found at /usr/lib/sane to the sane folder found at /usr/lib/x86_64-linux-gnu/sane.

   
   
   

   sudo ln -sfr /usr/lib/sane/libsane-smfp* /usr/lib/x86_64-linux-gnu/sane
   
   

   
   


2. 
   

   As root, edit the file 59-smfp_samsung.rules (you can find it in /etc/udev/rules.d) to include the following code/scanner number along with other Samsung model numbers which are already there:

   
   
   

   ATTRS{idProduct}=="2070", ENV{libsane_matched}="yes"
   
   

   
   

Voila. It should work like a charm.

I believe this bug mostly affects network scanners. Except with minor variations in the name/model numbers of other scanners, this workaround should work for other network scanners too. Check the bug-report link for Brother, Epson, and Xerox scanners.

For a Samsung Scanner/Printer M2885FW, which is connected over WiFi, and Ubuntu 18.04 a combination of two suggestions in this thread solved the problem with scanning: Rajasekharan N.'s answer and Jevgenij Evll's answer.

1. 
   

   I rebuilt the links found at /usr/lib/sane in the folder /usr/lib/x86_64-linux-gnu/sane by using following lines:

   
   
   

   sudo ln -s /opt/smfp-common/scanner/lib/libsane-smfp.so.1.0.1 /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1.0.1
   
   sudo ln -s /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1.0.1 /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1
   
   sudo ln -s /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so.1 /usr/lib/x86_64-linux-gnu/sane/libsane-smfp.so
   
   

   
   



2. After this step I un- and reinstalled the Samsung drivers.

For network Samsung scanners, put your scanner's IP address and optionally port anywhere in the file /etc/sane.d/xerox_mfp.conf:

tcp host_address [port] 

It worked with my C460, probably would work also with other scanners, check the respective sane config file and settings here:

• SANE supported devices


• sane-xerox_mfp man page

For my SAMSUNG M2070 running uninstall-scanner.sh and then install-scanner.sh again (with restarting afterwards) fixed the issue.
I also installed libsane and sane-utils from the proposed updates repo prior to the above, but not sure if this step is needed.

I tried Rajasekharan N.'s solution with Ubuntu 18.04 for Samsung 2070w and the newest uld driver downloaded from hp - scanner didn't work even connected via USB cable.

So

1. I removed the uld driver using the uninstall.sh provided with the uld driver


2. I reinstalled using the older Samsung uld driver (sadly I have no link for it) and it works again

I have a Samsung M2070 printer/scanner, had the same problem as you, and I fixed the problem by uninstalling Ubuntu 18.04 and reinstalling Ubuntu 16.04.

in ubuntu 18.04 LTS i had to replace libusb-0.1.so.4 with libusb-dev (the command for this task: sudo apt-get install libusb-dev).

i replaced libusb-0.1.so.4 with libusb-dev and now scanner works (sudo apt-get install libusb-dev
