kubuntu 16.04: error while loading shared libraries

[bafrog]

I previously used a very dusty version 12.04 of Xubuntu which did not work with PI anymore (since 01.08.04.1198) due to the old glibc version.
So I decided to renew my aged system and go for the latest LTS of Kubuntu 16.04 using PI-linux-x86_64-01.08.04.1198-20160221.

But now I get an error message about a missing library when starting PI via command line
(as the KDE launcher would do):
martin@castor:/opt/PixInsight/bin$ ./PixInsight.sh
/opt/PixInsight/bin/./PixInsight: error while loading shared libraries: libgstapp-0.10.so.0: cannot open shared object file: No such file or directory

The installation beforehand seemed to work well:
martin@castor:~/software$ sudo ./installer
[sudo] password for martin:

PixInsight X11 UNIX/Linux installer version 01.08.04.1198 Ripley

PixInsight will be installed with the following parameters:

Source installation directory ... /home/martin/software/PixInsight
PixInsight Core application ..... /opt/PixInsight
Application desktop entry ....... /usr/share/applications/PixInsight.desktop
Application icons directory ..... /usr/share/icons/hicolor
MIME type description file ...... /usr/share/mime/packages/PixInsight.xml
Create /bin launcher script ..... yes
Remove previous installation .... yes

==> Are you sure [yes|no] ? yes

Please wait while PixInsight is being installed...

* Previous PixInsight installation removed.

* PixInsight installation completed.

martin@castor:~/software$

For information:
$ uname -a
Linux castor 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux


Does anybody have an idea what I could be doing wrong? Is there really a library missing or is it just that LD_LIBRARY_PATH is pointing the wrong ways during startup?
I hope the destination folders during installation were correct - I just did not change them. Or is there a specific need for my distro maybe?

I would be very grateful for any help or hint

Hi Martin, only to add some information, I've tested with Kubuntu 14.04 and launch well from the console.

Your system lacks required dependencies. Try with the following:

sudo apt-get install libgstreamer-plugins-base

This should solve your issue on Ubuntu.

For info, on Ubuntu 16.04 I tried the command:

sudo apt-get install libgstreamer-plugins-base

which returned:

Unable to locate package libgstreamer-plugins-base

The command:

sudo apt-get install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev  libfreeimage3 libc6:i386

worked and allowed Pixinsight to run.

cheers,
Tom

Thanks Juan, Tom and Alejandro,

sorry for replying so late - I was busy with job and family. You solved my issue: more precisely finally it was Tom's hint that solved the issue: I just had to install one library which then automatically installed it's dependencies including  most of the other libraries that Tom had on it's command (I did not need libfreeimage3):

sudo apt-get install libgstreamer-plugins-base0.10-dev

I found that on my system version 1.0 of the library was initially installed. Now both are installed - 0.10 and 1.0 - hope it will not cause any interference.
PI runs as usual however.
