When python is not available, e.g. in firejail with some profiles
(for security reasons), gdb refuses to run:

zira:~> firejail --allow-debuggers --profile=firefox
zira% gdb
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Python path configuration:
  PYTHONHOME = (not set)
  PYTHONPATH = (not set)
  program name = '/usr/bin/python'
  isolated = 0
  environment = 1
  user site = 1
  safe_path = 0
  import site = 1
  is in build tree = 0
  stdlib dir = '/usr/lib/python3.11'
  sys._base_executable = '/usr/bin/python'
  sys.base_prefix = '/usr'
  sys.base_exec_prefix = '/usr'
  sys.platlibdir = 'lib'
  sys.executable = '/usr/bin/python'
  sys.prefix = '/usr'
  sys.exec_prefix = '/usr'
  sys.path = [
    '/usr/lib/python311.zip',
    '/usr/lib/python3.11',
    '/usr/lib/python3.11/lib-dynload',
  ]
Python Exception <class 'ModuleNotFoundError'>: No module named 'encodings'
Python not initialized

gdb should dynamically consider that python is optional and run
without python support in such a case.

Note that there is no issue with the dynamical linking against the
/usr/lib/x86_64-linux-gnu/libpython3.11.so.1.0 library; it is just
that the /usr/lib/python3.11 directory is not available.

Hello,

Could you use gdb-minimal instead?

Regards

gdb-minimal does not provide source highlighting, and there may be
other missing features that can be used in firejail.
