The error "OSError: [Errno 95] Operation not supported" typically occurs when you are trying to change the permissions on a file or directory that is located on a network file system (NFS) share or a shared folder that does not support the requested operation.

In your case, it seems that you are trying to read files from a shared folder that you can list but cannot read, and you are also unable to change the permissions using the chmod command.

One possible solution is to check the permissions and ownership of the files on the shared folder. Make sure that the permissions are set correctly and that you have the necessary permissions to read the files. You may also need to check the ownership of the files and ensure that you have the necessary privileges to access them.

Another possible solution is to check the configuration of the network file system or shared folder that you are using. Some network file systems or shared folders may have limitations or restrictions on the types of operations that can be performed on them. You may need to consult with the system administrator or IT team responsible for the shared folder to determine if there are any restrictions or limitations that may be causing the issue.
