在 Ubuntu 上安装 Gazebo 8.0 时软件包损坏

我正在尝试安装Gazebo 8.0 模拟器适用于 Ubuntu 16.04。我尝试了 .deb 包，它给了我这个 bash 脚本：

gazebo8_安装.sh：

# Description:
# This script installs gazebo onto an Ubuntu system.

codename=`lsb_release -sc`

# Make sure we are running a valid Ubuntu distribution
case $codename in
  "xenial" | "yakkety" )
  ;;
  *)
    echo "This script will only work on Ubuntu xenial, and yakkety"
    exit 0
esac

# Add the OSRF repository
if [ ! -e /etc/apt/sources.list.d/gazebo-latest.list ]; then
  sudo sh -c "echo \"deb http://packages.osrfoundation.org/gazebo/ubuntu ${codename} main\" > /etc/apt/sources.list.d/gazebo-latest.list"
fi

# Download the OSRF keys
has_key=`apt-key list | grep "OSRF deb-builder"`

echo "Downloading keys"
if [ -z "$has_key" ]; then
  wget --quiet http://packages.osrfoundation.org/gazebo.key -O - | sudo apt-key add -
fi


# Update apt
echo "Retrieving packages"
sudo apt-get update -qq
echo "OK"

# Install gazebo
echo "Installing Gazebo"
sudo apt-get install gazebo8 libgazebo8-dev

echo "Complete."
echo "Type gazebo to start the simulator."

我在终端上运行它并得到以下输出：

它说我持有损坏的包裹。但命令apt-mark showhold返回空。我尝试运行 Gazebo，但它gazebo7.0没有启动8.0。这里的问题是什么？我该如何解决？

答案1

在我的设置中，libsdformat5-dev发生冲突，因为 还存在以前的版本。libignition-math3的必需包中也存在冲突libsdformat5-dev。 解决依赖项冲突后，一切都安装正常。

答案2

我已按照描述的步骤操作这里最后出现了相同的错误消息，表明存在未满足的依赖关系libsdformat5

解决这个问题的方法是先安装 libignition-math3

sudo apt-get install libignition-math3

运行该程序确实解决了依赖项冲突。之后我安装了 gazebo8：

sudo apt-get install gazebo8

而且它有效，我希望这会有所帮助。
