Hi
Can anyone guide me on how to install LPP for LIGGGHTS 3.8.0 in Ubuntu 20.04.LTS. as I am finding error message as python 3 is installed instead of Python.

Thanks in advance.

LPP was written for Python 2, which is why Ubuntu 20.04 (where python points to Python 3) throws the “python 3 is installed instead of Python” error.

If your goal is converting LIGGGHTS dumps to VTK, I maintain a Python 3 rewrite of dump2vtk. It runs on Ubuntu 20.04+, includes a simple GUI for ease of use, and also supports CLI for batch processing. There’s a Windows binary installer as well (no Python required).
