类似问题的答案建议尝试手动安装软件包。但是fontconfig
,,,,和已经安装。所以所有名为依赖项的软件包都是如此libfontconfig1
。那么为什么它无法安装?libgtk2.0-0
libqt5svg5
libuuid1
libapache2-mod-php5
编辑:php7.0
我通过安装解决了这个问题libapache2-mod-php7.0
,但我仍然想了解这些令人困惑的错误消息。
按照要求:
$ sudo apt-cache policy libapache2-mod-php5
libapache2-mod-php5:
Installed: (none)
Candidate: 5.3.10-1ubuntu3.25
Version table:
5.3.10-1ubuntu3.25 500
500 http://us.archive.ubuntu.com/ubuntu precise-updates/main amd64 Packages

5.3.10-1ubuntu3 500
500 http://us.archive.ubuntu.com/ubuntu precise/main amd64 Packages
嗯……
$ grep precise /etc/apt/sources.list
(无输出)
我使用 GIMP 2.6,因为 2.8 太垃圾了。我忘了具体是怎么安装 2.6 的,但我觉得它类似于这个答案。这是否意味着尽管我从中删除了存储库,但其缓存中apt
仍然有内容?precise
sources.list
答案1
您正在尝试安装不受支持且不存在的软件包,因为 Xenial 默认php版本是php7.0
(没有任何php5.x
分支的包)并且相同阿帕奇2使用默认版本2.4.18
(以及其他版本)不能满足您所需的软件包依赖关系。
奇怪的是,您如何将输出发送到终端,
apt install libapache2-mod-php5
(或apt show
)通知根本没有候选(不存在)。似乎您在系统/缓存中有任何 Precise repo 或任何包,这会产生冲突。
尝试清理它并尝试按照以下步骤重新安装它:
- 从中删除任何现有的存储库精确 (12.04)使用终端或 GUI。
- 使用以下命令全面更新您的系统并清除旧软件包:
sudo apt update && sudo apt full-upgrade
。 - 清理系统中未使用/旧的软件包和文件:
sudo apt autoclean && sudo apt autoremove
。 - 使用 清空 apt 缓存
sudo apt clean
。 - 使用以下命令安装 mod php 包
sudo apt install libapache2-mod-php
(将安装libapache2-mod-php7
默认的 xenial 版本)
希望能帮助到你。
