The QT wallet does not start:

./bitcoin-qt в ubuntu 20.04?  qt.qpa.plugin: Could not find the Qt platform plugin "offscreen" in ""                                                  

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

If the "offscreen" plugin is missing, you may need to rebuild Qt with the necessary platform plugins. First, ensure you have the Qt source code:

 git clone https://code.qt.io/qt/qt5.git
 cd qt5
 git checkout <qt_version_tag>  # Replace <qt_version_tag> with the desired version tag, e.g., 5.15.2
  • Then configure and build Qt with the necessary platform plugins:

    ./configure -prefix /path/to/qt -opensource -confirm-license -nomake examples -nomake tests
    make install

    Replace /path/to/qt with the desired installation path.

After rebuilding Qt, you can follow the previous steps to rebuild Bitcoin Core and run it. This should ensure that the required Qt platform plugins, including "offscreen," are available.

Remember to replace <qt_version_tag> with the actual version tag of the Qt version you want to build.
