Set-up a Samsung CLX-3185 printer/scanner on Ubuntu 16.04

Version française

First of all, we have to add a server to the packages manager to get the needed packages for the set-up. This should be done with these commands:

sudo bash -c 'echo "deb debian extra" >> /etc/apt/sources.list.d/suldr.list'
sudo apt-get update
In the log messages returned by this command, you could see this one:
W: An error occurred during the signature verification.
The repository is not updated and the previous index files will be used.
GPG error: debian 
InRelease: Les signatures suivantes n'ont pas pu être vérifiées car la clé publique n'est pas disponible : NO_PUBKEY C95104E509BAC46D  NO_PUBKEY FB510D557CC3E840
This is due to unauthenticated packages. To fix it, we have to add the authentication key of the added server with this command:
sudo apt-get install suldr-keyring
Then, you can run again the update command to check that the error doesn't occur:
sudo apt-get update
We can now install the printer/scanner driver with the following command:
sudo apt-get install suld-driver-4.01.17
The version number can evolve, so if the previous command shows you this packet doesn't exist, check if there is no upgraded version of it.
