由于软件包损坏而陷入未满足的依赖关系的无限循环
Stuck in infinite loop of unmet dependencies due to broken packages
这个问题可能与其他问题重复，但是，我已经尝试了他们的解决方案，但没有成功。我最近使用以下命令删除了 ROS Indigo-
ravi@lab:~$ sudo apt-get remove ros-*
0 upgraded, 0 newly installed, 0 to remove and 12 not upgraded.
现在，我需要它。所以我尝试使用以下命令再次安装它-
ravi@lab:~$ sudo apt-get install ros-indigo-desktop-full

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ros-indigo-desktop-full : Depends: ros-indigo-perception but it is not going to be installed
E: Unable to correct problems, you have held broken packages
。
不幸的是，以上没有奏效。所以我尝试安装依赖项但没有成功-

我的 objective 是在我的 Ubuntu 14.04 LTS PC 上安装 ROS Indigo（不格式化 :D）
有什么解决办法吗？
我终于修好了。我不得不深入研究它，我终于意识到问题是由于 libusb.
为了解决这个问题，我先删除了libusb（对不起，我暂时不记得确切的版本）。之后，我运行apt-get autoclean。然后 apt-get update 和 apt-get upgrade 只是为了确保一切都在正确的地方。
最后，我使用 sudo apt-get install ros-indigo-desktop-full 并且成功了。
