ros 桌面完整未满足的依赖项

错误

我正在尝试在我的电脑上安装 ros 桌面完整版，如下所示 这些步骤一切都很好，直到步骤 1.4，准确地说

sudo apt-get install ros-kinetic-desktop-full

我出现以下错误：

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-kinetic-desktop-full : Depends: ros-kinetic-desktop but it is not going to be installed
       Depends: ros-kinetic-simulators but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

依赖树

我将在这里报告整个依赖关系树，其中我使用命令sudo apt-get install来处理每个列表元素左侧的所有依赖关系。我首先遵循模拟器的依赖关系：

  • ros-kinetic-desktop-full：依赖：ros-kinetic-simulators
  • ros-kinetic-simulators：依赖：ros-kinetic-rqt-common-plugins
  • ros-kinetic-rqt-common-plugins：依赖：ros-kinetic-rqt-web
  • ros-kinetic-rqt-web：依赖：ros-kinetic-webkit-dependency
  • ros-kinetic-webkit-dependency：依赖：python-pyqt5.qtwebkit
  • python-pyqt5.qtwebkit：依赖：python-pyqt5（= 5.8.2+dfsg-1+16.04+xenial+build19）但需要安装 5.8.2+dfsg-1+16.04+xenial+build21 E：无法纠正问题，您持有损坏的软件包。

然后我遵循桌面依赖关系：

  • ros-kinetic-desktop ：依赖：ros-kinetic-viz
  • ros-kinetic-viz：依赖：ros-kinetic-rqt-common-plugins
  • ros-kinetic-rqt-common-plugins：依赖：ros-kinetic-rqt-web
  • ros-kinetic-rqt-web：依赖：ros-kinetic-webkit-dependency
  • ros-kinetic-webkit-dependency：依赖：python-pyqt5.qtwebkit
  • python-pyqt5.qtwebkit：依赖：python-pyqt5（= 5.8.2+dfsg-1+16.04+xenial+build19）但需要安装 5.8.2+dfsg-1+16.04+xenial+build21 E：无法纠正问题，您持有损坏的软件包。

如你所见，两者都指向同一个包。但是当使用

 sudo apt-get install python-pyqt5

我明白了

python-pyqt5已经是最新版本（5.8.2+dfsg-1+16.04+xenial+build21）。

我尝试过的方法

  1. 手动将以下 deb 添加到/etc/apt/sources.list

    deb http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse  
deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse  
deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse  
deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse  
deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse  
deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse  
deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse  
deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse  
deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse  
deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse

  2. 使用以下命令安装 python-pyqt5pip3 install pyqt5

  3. 使用 apt 多次升级、更新、dist-update

  4. 安装时ros-kinetic-ros-base没有给出依赖项错误

  5. 使用sudo apt-get install python-pyqt5=5.8.2+dfsg-1+16.04+xenial+build19 在接受安装之前提供以下输出：

答案1

我刚刚遇到了一个与你非常相似的问题，但我通过添加解决了它

deb http://cz.archive.ubuntu.com/ubuntu xenial main universe

到 /etc/apt/sources.list 的开头。注意这句话中的“xenial”一词，它应该与您的 Ubuntu 版本相同。如果它不适合您，我建议您先删除 /etc/apt/sources.list.d/ros-latest.list，然后重试。

答案2

将以下软件包源添加到 /etc/apt/sources.list。

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse

deb http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial main restricted universe multiverse

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-security main restricted universe multiverse

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-updates main restricted universe multiverse

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-proposed main restricted universe multiverse

deb-src http://mirrors.ustc.edu.cn/ubuntu/ xenial-backports main restricted universe multiverse

现在，按照本指南中 1.2 的步骤操作关联
