Could not find the Qt platform plugin "xcb" in "" - qt

I made a simple "hello world" with Qt Designer and I compiled it with auto-py-to-exe. No error message during compilation but when I double click on the created executable then I have this in my terminal:
(venv) (base) saltz#saltz:~/Bureau/70 5 applications Qt/test/output$ ./main
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized.

But I don't understand the "ldd libxcb.so" command .
What can I do now ? My OS is lubuntu 20.04 .

i have the same problem with gambas3.
This application failed to start because it could not find or load the Qt platform plugin "xcb".
ldd the file /usr/lib/qt5/plugins/platforms/libqxcb.so
gaves missing libraries
libxcb-render-util.so.0 => not found
libxcb-image.so.0 => not found
libxcb-icccm.so.4 => not found
installing them fixes the problem.-

I'am not good at linux, so I don't know how to deal with it.
How can I start the R successfully? Thanks.
Finally, I run
mv /usr/lib64/R/lib/libRrefblas.so /usr/lib64/R/lib/libRblas.so and let R run successfully!

QtCreator does not start "could not load platform xcb" [Ubuntu 16.04]

I installed Qt5.7 including the Qtcreator using the installation tool "qt-unified-linux-x64-3.0.5-online.run" into the folder /usr/local/Qt

I can't pin the error. Relevant threads are for example https://forum.qt.io/topic/71369/failed-to-load-qt-platform-plugin-xcb/2, but libQt5XcbQpa.so.5.6.1 is not missing in my case. Any ideas?
The solution for me was to explictly point to the correct shared libraries using:
LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/ qtcreator

I ran into the problem on Ubuntu 16, error xcb. Using the verbose key, I realized that the package was missing: libxcb-xinerama0. After installation, everything worked.

Fedora 27 VTK 7.1.1 with Qt 5

I have an application that uses VTK and Qt 5. While running this I get following backtrace

It looks like there is some mismatch between QT 4 and 5 causing error in library initialization. So I checked the lddtree output

It shows the Qt4 dependencies along with Qt5 dependencies. Then I checked the Qt dependencies of libvtkGUISupportQt.so. That shows it depends on Qt4 only.

In vtk mailing list They say setting the variable VTK_QT_VERSION to "5" should work. But I doubt because the libvtkGUISupportQt.so depends on Qt4 as compiled. However I set that variable in my CMakeLists.txt. And as expected it didn't work.
set(VTK_QT_VERSION "5" CACHE STRING "Expected Qt version")
mark_as_advanced(VTK_QT_VERSION)
FIND_PACKAGE(VTK 7.0 REQUIRED COMPONENTS vtkGUISupportQt vtkIOImport)
message(STATUS ${VTK_MODULES_DIR})
INCLUDE(${VTK_USE_FILE})
# Find the QtWidgets library
FIND_PACKAGE(Qt5 COMPONENTS Core Widgets Svg Charts REQUIRED)
So now what is the solution ? I once heard VTK 7 links to Qt5. So was that wrong ? However in my Mac it worked fine even before 3 months. Now my Mac uses Vtk 8 with Qt5 (default). May be it was Vtk 7 with Qt5 few months back. I don't know because I have done some updates very recently.
I prefer installing with dnf So that I can easily ship. Both Vtk and Qt are installed with dnf (in Fedora) and brew (in Mac) But If I now compile and install Vtk8 from source would that conflict ?
Another tricky solution could be bypass QVTKWidget and create a QWidget that does the same job as QVTKWidget. If that is easy. I don't know how feasible that is.
Related Bug Report
While building Vtk with Qt5 there may be issues with other dependencies (I don't know, may be with python 3). But so far libvtkGUISupportQt can be compiled with Qt5. So I think there can be both libvtkGUISupportQt4 and libvtkGUISupportQt5 packaged in the binary distribution. The first one can be used for the dependent packages that have not been worked on yet.

asterisk: symbol lookup error: /usr/lib/libasteriskssl.so.1 After Installation of Asterisk 11.9.0

I have installed Asterisk 11.9.0, but when i try to start the Asterisk instance, i get this error:

Looking forward to your feedback. Thanks
You have remove all duplicates for libssl, if any
After that need install libssl-devel and recompile asterisk with your version of library.

Any help will be greatly appreciated.THANKS!
Perhaps you've got a 32 bit isql and unixODBC and you are attempting to use a 64 bit driver. What does the file command say for isql for instance (all components in the chain need to be the same). You could always try running under strace to see what system calls are failing.
