Hi.

PI not working in xubuntu since recent updates to 16.04.1 LTS.

Code: [Select]

./PixInsight: error while loading shared libraries: libssl.so.10: cannot open shared object file: No such file or directory

It looks that you tried to start PixInsight as follows:

Code: [Select]

/opt/PixInsight/bin>./PixInsight
./PixInsight: error while loading shared libraries: libssl.so.10: cannot open shared object file: No such file or directory
/opt/PixInsight/bin>
That will not work as several libraries (*.so) are not found

Either start it (correctly) with:

Code: [Select]

>./PixInsight.sh     

PixInsight Core 01.08.04.1198 Ripley (x64)
Copyright (c) 2003-2016 Pleiades Astrophoto
...
or by clicking on the application link which is integrated in your window manager, e.g. xfce4, gnome, etc...
The application link is created during PixInsight installation.

If you look quickly in ./PixInsight.sh you will see that the library path is there set

Code: [Select]

#!/bin/bash
appname=`basename $0 | sed s,\.sh$,,`
dirname=`dirname $0`
if [ "${dirname:0:1}" != "/" ]; then
   dirname=$PWD/$dirname
fi
LD_LIBRARY_PATH=$dirname/lib:$dirname
...
...

thus the required libraries will be found.

Cheers

Thanks Thomas.

The reason for posting is that PixInsight cannot be launched by the usual means; 'clicking the application link'. This led me to investigate further.

I did try ./PixInsight.sh

Code: [Select]

./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
This indicates further problems accessing libraries.

I cannot launch PI by any means, including after a new install.

[copello]

According to your error message, library libgstapp-0.10.so.0
is either not installed or not in the library path. On my Debian Jessie it is in package:

Code: [Select]

>apt-file search /usr/lib/x86_64-linux-gnu/libgstapp-0.10.so
libgstreamer-plugins-base0.10-0: /usr/lib/x86_64-linux-gnu/libgstapp-0.10.so.0
libgstreamer-plugins-base0.10-0: /usr/lib/x86_64-linux-gnu/libgstapp-0.10.so.0.25.0
libgstreamer-plugins-base0.10-dev: /usr/lib/x86_64-linux-gnu/libgstapp-0.10.so
Is the package libgstreamer-plugins-base0.10-0 installed on your system?

[astropixel]

Thank you. It is now. I don't recall uninstalling libgstreamer-plugins-base. I'm not sure it was ever installed.

[Juan Conejero]

Nothing to add to Thomas' excellent diagnostic and solution. *Never* try to run the PixInsight executable directly on Linux and FreeBSD. Always use the launcher script. If you have installed the application correctly, you can also say just 'PixInsight' from anywhere on your filesystem, since the installer program generates a launcher script on /bin.

I don't recall uninstalling libgstreamer-plugins-base. I'm not sure it was ever installed.

libgstreamer 0.10 is not installed on most Linux distros by default. The next version of the PixInsight core application does not have this dependency on deprecated packages (it has many more dependencies, actually, but on modern packages that should be more readily available).

[astropixel]

Thanks Juan and Thomas.

Just so there is no misunderstanding, PI would 'not' launch via the launcher.

I have installed PI as per instructions many times on my system and always use the launcher.

The reason for using the command line was to read the error output, only. Generally, a quick way to troubleshoot...

I presume that lbgstreamer was removed inadvertently by use of

$sudo apt-get autoremove

removing redundant packages installed for other than a PI dependency.

Because PI is not a .deb package there is no dependency check.

I guess there is a list of dependencies for Linux PI somewhere.

I'm on Kubuntu 16.10 and I'm having the same problem.

Snag is I can't find a repo to download the libssl.so.10 from. Is there a way to fix the problem ? Just bought a second hand dual xeon machine to run PixInsight on so did fresh Kubuntu install

Code: [Select]

tim-dell@tim-dell:/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 tim-dell@tim-dell:/opt/PixInsight/bin$                               

Thanks

Hi Tim,

Have you installed the

Code: [Select]

libgstreamer-plugins-base0.10-0 deb package?

Cheers
 Thomas

[TimScottz8]

No. The 0.10 version is not available in the standard repositories for Kubuntu 16.10. Only 1.0-0 . I tried installing the 0.1 version by download of the package but it then complained of broken dependencies. Do you have a repo I can add to apt that will allow it's installation ?

[copello]

I don't know whether these packages will work for 16.04.1 LTS. If I am not mistaken, then
Ubuntu Xenial (16.04) is derived from Debian Stretch (currently Testing). So probably the following could work (this works for Debian Stretch):

Code: [Select]

> mkdir debs && cd debs
> wget http://fr.archive.ubuntu.com/ubuntu/pool/main/g/gst-plugins-base0.10/libgstreamer-plugins-base0.10-0_0.10.36-1_amd64.deb
> wget wget http://fr.archive.ubuntu.com/ubuntu/pool/universe/g/gstreamer0.10/libgstreamer0.10-0_0.10.36-1.5ubuntu1_amd64.deb
> sudo dpkg --install *

[TimScottz8]

That worked thanks. Just hope the PixInsight soon uses the new packages so I can remove these older ones. Just got to remember to do it !

[Pierre]

I just had the same problem to a T! Thanks for that solution copello!
