今天继续记录一下之前升级 Ubuntu 遇到的问题，这个问题比较难搞，由于之前别人装的系统是中文的，所以下面的问题描述也出现了中文错误信息：

在处理时有错误发生：

click

click-apparmor

libunity-scopes1.0:amd64

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

简单的说就是 click、click-apparmor、libunity-scopes1.0 这三个包有问题，导致操作没能顺利完成。为了解决这个问题，可是花了不少时间，下面做个记录。

由于没有记录当时具体问题信息，大致找一下网上别人的错误信息如下。

二、解决方法

方法一：

First, I went to /var/lib/dpkg/info/:

cd /var/lib/dpkg/info/

Then, I removed the lines pertaining to the packages which caused the problems. In my case, I had to do:

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

After that, I typed:

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

方法二：

I don’t now if it doomed something else on the system but it works out for my problem:

sudo -i                       # to be the superuser
dpkg --purge unity-plugin-scopes:amd64 url-dispatcher:amd64 url-dispatcher-tools unity8-common unity8 unity-greeter-session-broadcast unity8-desktop-session   # to remove the 7 last dependencies 

then, remove libunity-scopes1.0:amd64 manually cause dpkg –dpkg had some issues with this one so with command line:

rm -r /usr/share/doc/libunity-scopes*
rm /var/lib/dpkg/info/libunity-scopes*
rm /usr/share/apport/package-hooks/libunity-scopes1.0.py
rm /var/crash/libunity-scopes*

then you can use:

dpkg --purge libunity-scopes1.0:amd64
apt-get install -f
apt autoremove
