I am trying to install LPP (LIGGGHTS® Post-Processing) following the official installation guide. However, I encountered issues when trying to clone the repository.
1.I attempted to clone the repository using: git clone git@github.com:CFDEMproject/LPP.git
But it returned the following error:
ERROR: Repository not found.
fatal: Could not read from remote repository.
2. I checked my SSH connection to GitHub with: ssh -T git@github.com
The response was: Hi [xxxxx]! You've successfully authenticated, but GitHub does not provide shell access.
3. I also tried cloning using HTTPS: git clone https://github.com/CFDEMproject/LPP.git
But still received a "Repository not found" error.
there is 404 error at https://github.com/CFDEMproject/LPP.git
Questions:
Is the LPP repository still available at github.com/CFDEMproject/LPP? Has it been moved or deleted?
Do I need special permissions or a different repository URL to download LPP?
Is there an alternative way to install LPP for post-processing LIGGGHTS® simulations?
Could there be an issue with my GitHub SSH key or authentication settings?
Any guidance or updated repository links would be greatly appreciated!

Alternative to LPP (Python 2): Python 3 dump2vtk
There have been many reports that LPP no longer works reliably on modern environments.
LPP was developed for Python 2 and is based on the older Pizza.py toolkit; as a result, it often runs into compatibility issues and bugs on systems where Python 3 is the default (e.g., Ubuntu 20.04+).
If your goal is converting LIGGGHTS dump files to VTK, I have developed a new program in Python 3:
