我在 时遇到libgphoto2-port12_2.5.14错误apt upgrade，但使用 无法解决apt -f install。我没有安装任何新东西，只是执行了常规更新、升级。我在 上看到了其他类似的问题未满足的依赖项——libgphoto2-port12但目前该事宜仍处于搁置状态，我无法发表评论。
尝试了他们所有的“解决方案”，但都没有成功，包括sudo apt-get dist-upgrade -f他们给出的解决方案。我的信念是：
$ uname -r
4.4.0-81-generic
$ lsb_release -a

有问题的错误是：

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:

我需要帮助，因为我无法安装任何软件包。如果有人认为这与 ubuntu 无关，请告诉我哪个论坛是合适的。谢谢
答案1
libgphoto2-port122.5.14+201706200750~ubuntu16.04.1:{i386:amd64} 版本来自 ppa:mutlaqja/ppa，而不是来自 ubuntu 存储库。我最终自己解决了这个问题，直接从http://pkgs.org/download/libgphoto2-port12和：
$ wget http://archive.ubuntu.com/ubuntu/pool/main/libg/libgphoto2/libgphoto2-port12_2.5.10-3_amd64.deb
$ wget http://archive.ubuntu.com/ubuntu/pool/main/libg/libgphoto2/libgphoto2-port12_2.5.10-3_i386.deb
然后，使用以下命令安装它们：
$ sudo dpkg -i libgphoto2-port12_2.5.10-3_i386.deb
$ sudo dpkg -i libgphoto2-port12_2.5.10-3_amd64.deb
最后，我使用以下命令删除了有问题的 ppa（暂时删除，直到错误得到解决）：
$ sudo add-apt-repository --remove ppa:mutlaqja/ppa
之后，我重新启动以清理缓存并执行标准 apt-get update 和 upgrade，没有错误。现在我又可以自由安装新软件包了。
答案2
“libgphoto2-port12：损坏：libgphoto2-port12：i386（！= 2.5.14+201706200750~ubuntu16.04.1）”
64 位和 32 位版本必须相同。
将 libphoto2-port12 升级到 ver 2.5.14 或者将 libphoto2-port12;I386 降级到 ver 2.5.9-3
