更新我的包列表时如何修复错误？

当我尝试更新我的Ubuntu 16.04时出现此错误。

错误：

W: The repository 'http://ppa.launchpad.net/upubuntu-com/network/ubuntu xenial Release' does not have a Release file. N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use. N: See apt-secure(8) manpage for repository creation and user configuration details. E: Failed to fetch http://ppa.launchpad.net/upubuntu-com/network/ubuntu/dists/xenial/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. 

这是什么错误，我该如何解决？

该错误不会造成任何伤害（至少），但您可以通过执行sudo nautilus手动删除它们，然后导航到/etc/apt/sources.list ，然后删除不需要的文件，可能是与upubuntu.com相关的文件因为它没有Ubuntu 16.04的任何文件。
