我将Django项目迁移到了一个新的生产服务器上。在以前的生产服务器上，一切正常。在迁移过程中，我升级到了Ubuntu 20.04和Django 4.0.3。现在，除了上传文件外，一切都恢复正常。
当我尝试创建Invoice对象的实例时，只要我不尝试上传文件，它就可以工作。添加带有文件的发票会出现以下错误：

文件已上载到正确的(cifs已安装(文件夹，但由于某种原因，无法将包含文件链接的对象实例添加到数据库中？
我想问题出在某种许可问题上。我试着通过将所有设置为777来解决这个问题，这样我至少可以看看这是否解决了问题，但事实并非如此。/var/www/html/media的文件夹权限当前为：
drwxrwxrwx 2根目录0 3月17日08:57发票
chown由于某种原因不起作用(我读到这与cifs装载有关？(，但var-www也不是以前服务器上发票文件夹的所有者，这很好。。。
