Install CASES 4.3.1 on (K)Ubuntu 18.04 - solution that worked for me

Recommended Posts



CAESES 4.4.1 comes with the lastest libpng12.so.0.59.0 and all the symbolic links set correctly (so forget about steps 1. - 4- below).


However, removing libz (step 5) is still required under (K)Ubuntu 18.04.





CASES 4.3.1 doesn't run on (K)Ubuntu 18.04 out of the box because it requires libpng12 that isn't readily available for 18.04.


Here my work around:


  1. Get libpng12 (64-Bit) from https://packages.ubuntu.com/xenial/amd64/libpng12-0/download
    (This is the latest version for (K)Ubuntu 16(!).04)
  2. Extract libpng12.so.0.54.0 from the downloaded .deb package (I used ark and just looked through the file until I found it in /lib/x86_64-linux-gnu)
  3. Copy libpng12.so.0.54.0 to the lib-directory of your CAESES-Installation (usually something like ~/CAESES_4.3.1_Linux.x86_64/lib/Linux.x86_64)
  4. Set the symbolic link ln -s libpng12.so.0.54.0 libpng12.so.0 (in the lib directory)
  5. REMOVE libz.so  libz.so.1  libz.so.1.2.5 from yor CAESES-lib-directory
    (They are too old and apparently the newer version comes with 18.04)
  6. Make sure your proprietary graphics driver is installed.

Worked like a charm for me. Hope it helps.

Hi Bodo


Thanks, your solution did help me the libpng12-error

I also needed to install the canberra-gtk-module, by simply doing sudo apt install canberra-gtk-module


Afterwards I had a problem with the licensing:  it returned the error:

The license file contains hardware keys not corresponding to this workstation.
Please send us an email with the failed identifiers!

So i tried to start caeses by "./CAESES -resetauth"
But it didn't work out. So Joerg, here comes my e-mail :).
