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.

Use a Python-3 replacement for dump→VTK
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).

LPP Python3
We actually have a Python3 version of LPP (as well as the original version) available at https://github.com/ParticulateFlow/LPP/tree/python3
