@宏沉一笑先尝试全部卸载下.不行用docker版本的吧,我一直在用docker版的,更方便

宏沉一笑

@小鱼现在是解决问题了，不是换docker了。我要是用docker就不测试这个了

小鱼

@宏沉一笑造成依赖问题一般是第一次安装中某些包因为网络问题安装失败，导致依赖其的包失败，核心解决方法就是从失败的包装起。
除此我也没其他办法了

宏沉一笑

@小鱼现在是使用你的一键安装脚本出错了。再说了，我都试了好几次了。都是这个错误。其他人也是这个问题。

@小鱼我尝试过手动安装失败的包，问题是没有符合版本要求的包，那个包我换了几个源都找不到符合要求的版本

小鱼

@宏沉一笑一键安装也只是比手动多尝试几个源而已，如果一键安装出错，手动装八成也会出错

小鱼

@1577251018 你贴一下具体的，我这边针对22.04最新版本搞个ubuntu做一下测试

小鱼

@1577251018 测试了下,确定了问题存在,这次应该是ROS2官方的包发错了,或者是国内的源同步错误,我切换到官方源在试试

he following packages have unmet dependencies:
 libignition-math6-dev : Depends: libignition-cmake2-dev (>= 2.13.0) but 2.12.1-2~jammy is to be installed
E: Unable to correct problems, you have held broken packages.
Run CMD Task:[sudo apt install   ros-humble-desktop -y]
[-]Result:code:100                           ion-cmake2-dev (>= 2.13.0) but 2.12.1-2~jammy is to be installed

找到了,该问题确实是官方引起的,已经修复了,需要等待一段时间才能同步到ros2源上

@小鱼官方源我尝试过了，也不行

小鱼

@1577251018 需要等待一段时间，一般每次编译和同步都至少要10h以上

小鱼

@OpenKai 该问题目前已经被修复了
