It appears ghidragdb is missing from the remote system. This can happen if you
|
|
forgot to install the required package. This can also happen if you installed
|
|
the packages to a different Python environment than is being used by the
|
|
remote's gdb.
|
|
|
|
This script is about to offer automatic resolution. If you'd like to resolve
|
|
this manually, answer no to the next question and then see Ghidra's help by
|
|
pressing F1 in the dialog of launch parameters.

|
|
WARNING: Answering yes to the next question will invoke pip to try to install
|
|
missing or incorrectly-versioned dependencies. It may attempt to find packages
|
|
from the PyPI mirror configured on the REMOTE system. If you have not configured
|
|
one, it will connect to the official one.
|
|
|
|
WARNING: We invoke pip with the --break-system-packages flag, because some
|
|
debuggers that embed Python (gdb, lldb) may not support virtual environments,
|
|
and so the packages must be installed to your user environment.
|
|
|
|
NOTE: This will copy Python wheels into the HOME directory of the user on the
|
|
remote system. You may be prompted to authenticate a few times while packages
|
|
are copied and installed.
|
|
|
|
NOTE: Automatic resolution will cause this session to terminate. When it has
|
|
finished, try launching again.
