@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
-
@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
-
@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 -
@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
-
@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
-
@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
-
@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

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
具体见:

@小鱼 官方源我尝试过了，也不行
-
@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
-
@OpenKai 该问题目前已经被修复了
