由于损坏的包而陷入未满足的依赖项的无限循环

  • 772

我在SO中发布了这个问题，但没有找到任何建议。因此，我在这里发布希望。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，但没有取得任何成功。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 9 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

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-

ravi@lab:~$ sudo apt-get install -f

我尝试手动安装依赖ros-indigo-perception项但没有机会-

我尝试了更多并考虑安装另一个依赖ros-indigo-perception-pcl项，但徒劳无功-

ravi@lab:~$ sudo apt-get install ros-indigo-perception-pcl

我的目标是在我的 Ubuntu 14.04 LTS PC 上安装 ROS Indigo（无需重新安装操作系统：D）

请问有什么办法吗？

package-management dependencies apt ros 14.04

  1. 尝试

    sudo apt update
sudo apt upgrade

    之后

    sudo apt install -f

    或者你可以试试

    sudo apt autoremove

    更新有可能帮助您解决依赖问题

  2. Best Answer

    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，我首先删除了libusb（对不起，我目前不记得确切的版本）。之后，我运行apt-get autoclean. 然后只是为了确保一切都在正确的地方apt-get update。apt-get upgrade

    最后，我用sudo apt-get install ros-indigo-desktop-full了它，它奏效了。

    笔记

    重新启动PC后，登录不起作用，并显示Failed to start sesssion。不要惊慌，在登录屏幕按CTRL+ ALT+ F1。它将带您到航站楼。使用您的用户名和密码登录。最后使用以下命令恢复桌面sudo apt-get install ubuntu-desktop
