Hi Forums,
Now I tried to install CFDEM. But while I tried to clone LPP from github. the error occurred.
```
$ sudo git clone git://github.com/CFDEMproject/LPP.git lpp
remote: Support for password authentication was removed on August 13, 2021.
remote: Please see https://docs.github.com/en/get-started/getting-started-with-git/about-re... for information on currently recommended modes of authentication.
fatal: Authentication failed for 'https://github.com/CFDEMproject/LPP.git/'
```
then I tried to download zip.file from "https://github.com/CFDEMproject/LPP.git"
But also, 404 message is displayed.
I would like you to give me a help to solve this problem.
thank you.

Cannot Access LPP Repository — Alternative Tool: D2V-dump2vtk
Hi—this isn’t on your side. The LPP repository on GitHub appears to be unavailable now (404 / “repository not found”), so the clone command you tried can’t succeed. Even switching auth methods won’t help because the repo itself isn’t accessible.

As a drop-in replacement for converting LIGGGHTS/CFDEM dump files to VTK/VTU, use this open-source tool instead:
D2V (dump2vtk)
Repo: https://github.com/opendemjapan/D2V-dump2vtk
Converts particle dumps and force-chain (pair/local) dumps to VTK/VTU
Works via GUI or CLI; supports multiprocessing and chunked reads for large files

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