What could be the problem here?

Hi @pswiatki, The reason is that the app is ~freezed~ frozen by pyinstaller on Ubuntu 16.04 LTS. It includes lots of system libraries and sometimes version of those ~'freezed'~ frozen (included) libraries are not compatible with other libraries in your system.

As a workaround: try to remove (or rename at first try) libjpeg.so.8 from <path_to_pw-sat2-gs>/main directory and run application again. Then this lib should be loaded from your system.

Sorry for that, I know that this method of providing the app is not perfect, but it was the only feasible one.

I see.... yes, I was actually curious about that statement in the wiki (please, correct in the WIKI text): "frozen". Checking if it will pick up the proper lib... Will keep you posted.

pswiatki commented 5 years ago

After renaming libjpeg.so.8 the functionality started working. Thanks for you advice.

pswiatki commented 5 years ago

Did not take into account the fact that the app came with its own set of "frozen" libraries. After follwing the advice provided by @begreeen it started working properly.
