我很难将owncloud从9.0.1升级到9.0.4。我已经为owncloud设置了适当的豁免，因为以前的系统范围apt-get upgrade来电是'upgrading' owncloud from 8.x to 4.x。但到目前为止升级了apt-get upgrade owncloud已经运作正常。现在，我正在点击：
root@raspi:/home/pi# apt-get install owncloud

php-doctrine-dbal is already the newest version (2.5.4-2).
php-pimple is already the newest version (3.0.2-2).

php-doctrine-dbal和php-pimple是最新版本，为什么apt-get没有想到？我已尝试投放apt-get install -f，报告0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded。但是不能解决问题。非常感谢。

尝试使用
进行安装aptitude install owncload
aptitude 应自动查看并安装依赖项。
这里的问题似乎是包 php-dochtrine-dbal 和 php-pimple 太新了。
