I tried your solution:

Do this:
1. Remove the repository.
2. sudo apt update
3. Add the repository.
4. sudo apt update
5. Install suldr-keyring.
6. sudo apt update

suldr.gpg is no longer the active key.  This should be a one-time error that is cleared after suldr-keyring is installed.

-- But with no success :-(((

I found an other way to solve the problem:

1. Download the deb-keyring-file "suldr-keyring_1_all.deb".
2. Extract the keyfile "suldr-keyring.gpg" from the downloaded deb-file (it's an archive file) into a folder.
3. If not installed, install "gui-apt-key": sudo apt-get install gui-apt-key
4. Start "gui-apt-key": sudo gui-apt-key
5. Import the extracted keyfile with the started program "gul-apt-key" (import file) from the folder.
6. Renew and check the package list: sudo apt-get update
   (it should work)

Thank you very much for your answer. When Ubuntu 14.04.1 comes out, i will upgrade to this LTS fearlessly.

Samsung SCX-4216F works fine (via usb): Ubuntu 12.04 LTS - printing and scanning (scanning: xsane-frontend).

A new LTS-Version (Ubuntu 14.04) will replace the older one in the next month. Have we to do anything?

Best regards
