深度软件中心不能打开,一直都是"加载中,请稍后..."的页面.
我用sudo apt-get update有以下的错误:

W: 无法下载 http://packages.linuxdeepin.com/deepin/ ... /InRelease  Unable to find expected entry 'restricted/source/Sources' in Release file (Wrong sources.list entry or malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

请问怎样解决啊?
