Contact the administrator of the file server to apply for the write permission for the user.
Cause one: If the type of the file server is NFS, it indicates that the UID and GID of the user prohibits the user from uploading, deleting, and renaming files.
An owner is the creator of the shared file.
A user of the same group and the owner have the same GID, but different UIDs.
The GIDs and UIDs of other users are different from those of an owner.
Cause two: If the type of the file server is SMB, the current user only has the read permission for the shared file resource, but has no write permission
