我对 Ubuntu 还比较陌生。几天前，我从 14.04 升级到了 16.04。升级后，我既不能安装新软件，也不能升级操作系统。当我输入
sudo apt-get upgrade
我得到这是我的输出：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Calculating upgrade... Done
The following packages will be upgraded:
apt apt-transport-https apt-utils gcc-doc libapt-inst2.0 libapt-pkg5.0

使用下面的错误代码，我在 AskUbuntu 中搜索解决方案，但找不到有效的解决方案。

我在软件中心有 gcc-doc 等待升级。当我尝试在软件中心升级它时，它花了很长时间，并且没有升级。在 Synaptics 中，它因 gcc-doc 而停止升级。
非常感谢您的帮助。

我在这里遇到了同样的问题。然后经过谷歌搜索，我找到了解决方案（我希望如此）如何修复“包处于非常糟糕的不一致状态”错误？
跑步：
sudo mv /var/lib/dpkg/info/<packagename>.* /tmp/
sudo dpkg --remove --force-remove-reinstreq <packagename>
sudo apt-get remove <packagename>
sudo apt-get autoremove && sudo apt-get autoclean
