升级 Ubuntu 17.04 后，软件包系统崩溃了。当我执行以下任何命令时，都会出现一些错误。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
click-apparmor : Depends: python3-apparmor-click (= 0.3.17) but 0.3.18 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我也尝试过以下解决方案，但是没有效果。
有人知道如何在不重新安装 Ubuntu 的情况下修复它吗？
答案1
我认为我找到了一个解决方案，但也有一个很大的警告：它有效，但我无法解释原因。
首先，我去了/var/lib/dpkg/info/：
cd /var/lib/dpkg/info/
然后，我删除了与导致问题的软件包相关的行。就我而言，我必须这样做：
sudo rm -r python3-apparmor-click.*
sudo rm -r click-apparmor.*
sudo rm -r click.*
sudo rm -r ubuntu-app-launch.*
sudo rm -r url-dispatcher-tools.*
sudo rm -r url-dispatcher:amd64.*
sudo rm -r libunity-scopes1.0:amd64
之后，我输入：
sudo apt purge python3-apparmor-click
sudo apt purge click-apparmor
sudo apt purge click
sudo apt purge ubuntu-app-launch
sudo apt purge url-dispatcher-tools
sudo apt purge url-dispatcher:amd64
sudo apt purge libunity-scopes1.0
在那之后，
sudo apt update
最后，
sudo apt dist-upgrade
它运行正常，并更新了我的软件包。所有软件包问题似乎都消失了。
答案2
升级到 Ubuntu 17.04 后我遇到了同样的问题，这对我有用：
sudo -H pip3 uninstall click
sudo apt install python3-click-package
sudo apt upgrade
sudo apt autoremove
不确定为什么（也许 pip 的点击版本与 Ubuntu 所依赖的版本不同？）但这解决了这个问题。
答案3
首先删除 python'点击' 包使用pip：
pip uninstall click
如果你使用python3： pip3 uninstall click
然后通过以下方式修复软件包易于：
sudo apt clean
sudo apt install -f
答案4
选项 1: 查找这个外部点击包：
sudo updatedb locate -ir python.*click然后手动删除它，如果有疑问，请将输出添加到问题中。
选项2：如果你仍然处于问题中提到的状态：

cd /var/lib/dpkg/info/ sudo mv click-apparmor:amd64.prerm click-apparmor:amd64.prerm.backup sudo dpkg --force-depends -r click-apparmor尝试使用以下方法安装新包：
sudo apt -f install如果有新的错误，请将其添加到问题中。
