如果您自己的Cloud安装程序在Debian上运行并且已随软件包一起安装，则在运行" apt-get update or upgrade"时可能会得到以下结果：

The following packages were automatically installed and are no longer required

全输出：

# apt-get upgrade

Use 'apt-get autoremove' to remove them.
Done

这可能是在先前通过运行" apt-get dist-upgrade"进行升级之后发生的，并且程序包管理器不知道是否使用了这些程序包，并且没有任何依赖性。
当然，删除它们将删除您自己的Cloud安装，您可能不想应用推荐的命令并删除它们！

取而代之的是，您可能要告诉APT对其进行标记，因此直到有新版本发布时，它才不会抱怨。

只需运行以下命令：

apt-mark owncloud-3rdparty owncloud-app-activity owncloud-app-encryption owncloud-app-external owncloud-app-files owncloud-app-files-external owncloud-app-files-locking owncloud-app-files-pdfviewer owncloud-app-files-sharing owncloud-app-files-texteditor owncloud-app-files-trashbin owncloud-app-files-versions owncloud-app-files-videoviewer owncloud-app-firstrunwizard owncloud-app-gallery owncloud-app-provisioning-api owncloud-app-templateeditor owncloud-app-user-external owncloud-app-user-ldap owncloud-app-user-webdavauth
