Webmin 正在升级软件包，之后出现了问题，现在我无法安装任何东西。甚至我的 Apache 服务器也宕机了。当我输入
apt-get install apache2
我收到这个错误
The following packages have unmet dependencies:
apache2 : Depends: apache2-mpm-worker (= 2.2.22-6ubuntu2.3) but it is not going to be installed or
apache2-mpm-prefork (= 2.2.22-6ubuntu2.3) but it is not going to be installed or
apache2-mpm-event (= 2.2.22-6ubuntu2.3) but it is not going to be installed or
apache2-mpm-itk (= 2.2.22-6ubuntu2.3) but it is not going to be installed
Depends: apache2.2-common (= 2.2.22-6ubuntu2.3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
然后我跑去apt-get dist-upgrade
拿了这个
The following packages have been kept back:
libtiff4 libxml2 rpm-common
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.
请帮忙
