我到处搜索但找不到解决方案。
如果我跑步update-manager，软件更新程序开始加载，但随后我得到了崩溃报告. 回溯的部分内容如下：

现在，如果我尝试，sudo apt-get upgrade我会得到以下结果：

如果我尝试，也会得到相同的输出sudo apt-get autoremove。我正在使用Ubuntu 16.04（4.8.0-49-通用）。
我到处寻找答案，但没有任何东西可以解决我的问题。
答案1
我在 16.10 上遇到了同样的问题，升级到 17.04 也没有帮助。我很确定问题是由于 python3 包冲突引起的，查看异常的跟踪，它似乎正在使用来自/usr/lib/python3（apt managed）和来自/usr/local/lib/python3.5（pip managed）的包。我删除了所有 pip 安装的包，重新安装了 update-manager/python3-aptdaemon/etc，但没有用... 经过一些额外的尝试，删除和清除所有内容，然后重新安装，似乎 update-manager 在使用synaptic后端时可以正常工作，而不是aptdaemon。到目前为止一切都很好。不幸的是，我无法提供任何步骤来重现或解决这个问题。
