ubuntu 18.04期与数字化

Question

我刚刚升级到18.04，并试图安装升级和或新的程序通过终端。我收到以下信息

digikam-private-libs : Depends: libkf5sane5 (>= 4.3.4) but it is not going to be installed
                        Depends: libqtav1 but it is not going to be installed
                        Depends: libqtavwidgets1 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
i have tried  sudo apt --fix broken install and get this message.dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

E: Sub-process /usr/bin/dpkg returned an error code (1)

我尝试过apt remove digikam和apt purge digikam并收到了这条消息

 Reading package lists... Done

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 digikam-private-libs : Depends: libkf5sane5 (>= 4.3.4) but it is not going to be installed
                        Depends: libqtav1 but it is not going to be installed
                        Depends: libqtavwidgets1 but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

我试着安装智能，并得到同样的信息。Digikam显示为没有安装在软件中心，当我按下安装时，我得到了一个错误，message.Everything似乎没有问题。谢谢你，，，雅克

似乎在两个版本(16.04和18.04)之间存在打包错误。

因此，我们可以强制安装这些软件包：

sudo dpkg -i --force-all /var/cache/apt/archives/libkf5sane5_17.12.3-0ubuntu1_amd64.deb
sudo dpkg -i --force-all /var/cache/apt/archives/libqtav1_1.12.0+ds-4build3_amd64.deb
sudo dpkg -i --force-all /var/cache/apt/archives/libqtavwidgets1_1.12.0+ds-4build3_amd64.deb

然后继续进行包安装。

sudo dpkg --configure -a
sudo apt-get install -f

为了确保升级所有包依赖项，并使用

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install --reinstall libkf5sane5 libqtav1 libqtavwidgets1
