Short description of error
I have a model with vertex groups in Blender on Windows. I save the file (I saved it as a new file to make sure it actually gets updated), push it to my git repository and download it on my Linux laptop. But when I open the binary on Linux, the vertex group is gone. I tried multiple times. I checked that the .blend file as well as the .blend1 file are being transferred correctly, I created a copy of the file, I removed the repository and cloned it again, but the vertice groups never exist on the Linux computer. It is really weird, because I was reimporting the COLLADA-Model in Linux to get the vertices again and created a new file from that, which still has the vertex groups. But I think I never opened it on Windows. So there seems to be some relation between opening and saving the file in Windows and the vertex groups disappearing on Linux.

Exact steps for others to reproduce the error
Create a blender file with a model that has skeleton, vertex groups and shape keys on Windows.
Create a git repository.
Push the file to the repository and download it onto a Linux PC.
Open the file in Linux.

Is Blender version on Linux same as in Windows? Can you provide .blend file you have problems with?

On Linux the blender version is: 2.82 (sub 7), branch, commit date and hash "unknown".
So it might also be an issue with version compatibility. However, that would be a very problematic issue. I got the blender version on Linux with apt-get, so it is the newest, that is proposed by the PPA.
mrp.blend

I created a minimal reproducible example of the issue. Assigned a vertex group on Linux (Blender version 2.82), opened the file on Windows, saved it, opened it on Linux again and the vertex groups are gone.

Thanks for info. There have been change in Blender version 3.0 - 3b6ee8cee7 and this is expected to happen. You can see warning when you open file.

You can either use interchange format or you have to update Blender version to at least 3.0. Version 2.82 is 2 years old, so perhaps you may need to update apt database as well.

In any case this is expected behavior so will close this report.

It won't help to update the apt database, the Blender versions in the distribution repositories are usually always out of date.
For Linux, use either the packed version (tar.xz) or you use a ppa, which has to be set up (if available) ; )
