   Hello.   
      
   Version 3.9.2 is in salsa but it has not been uploaded yet.   
      
   I tried the proposed patch on top of version 3.9.2 currently in salsa   
   and this is what I got:   
      
      
   * Creating isolated environment: venv+pip...   
   The virtual environment was not created successfully because ensurepip is not   
   available.  On Debian/Ubuntu systems, you need to install the python3-venv   
   package using the following command.   
      
       apt install python3.13-venv   
      
   You may need to use sudo with that command.  After installing the python3-venv   
   package, recreate your virtual environment.   
      
   Failing command: /tmp/build-env-95wnng21/bin/python3.13   
      
   make[3]: *** [Makefile:17: sdist] Error 1   
   make[3]: Leaving directory '/build/reproducible-path/biosig-3.9.   
   /biosig4c++/python'   
   make[3]: Entering directory '/build/reproducible-path/biosig-3.9   
   1/biosig4c++/python'   
   python3.14 -m build --sdist   
   * Creating isolated environment: venv+pip...   
   The virtual environment was not created successfully because ensurepip is not   
   available.  On Debian/Ubuntu systems, you need to install the python3-venv   
   package using the following command.   
      
       apt install python3.14-venv   
      
      
   I hope Andreas can fix this and complete the upload.   
      
   (While I'm also a team member, I'm not confident enough yet to make   
   uploads for new upstream releases).   
      
   Thanks.
