如何安装apt-get找不到的依赖？

空白

我在安装gazebo一个小插件时，在github上面找到一个相关的功能包，但是通过rosdepc发现在当前版本ubuntu22.04 缺少相关依赖，如果知道名字，有什么办法不通过apt-get instal来安装相关依赖吗？

rosdep check --from-path src --ignore-src -r -y
All system dependencies have been satisfied
ERROR[ign_ros2_control]: No definition of [ignition-gazebo3] for OS version [jammy]
	rosdep key : ignition-gazebo3
	OS name    : ubuntu
	OS version : jammy
	Data:
debian:
		  buster:
		  - libignition-gazebo3-dev
		ubuntu:
		  focal:
		  - libignition-gazebo3-dev

上面代码显示在focal版本有相关依赖，我尝试将ubuntu的os版本换成20.04

rosdep install --from-path src --ignore-src -r -y --os=ubuntu:focal
executing command [sudo -H apt-get install -y libignition-gazebo3-dev]

E: 无法定位软件包 libignition-gazebo3-dev
ERROR: the following rosdeps failed to install
  apt: command [sudo -H apt-get install -y libignition-gazebo3-dev] failed
  apt: Failed to detect successful installation of [libignition-gazebo3-dev]

对此可以意识到其实rosdep 就是通过apt-get install来安装相关依赖，所以想问下大家如何安装apt在当前版本找不到的依赖？

@空白 rosdep其实就是调用的apt来安装，apt安装不了的，只能自己手动下载源码编译了，也就是常说的编译安装

@小鱼那如果我想安装像是libignition-gazebo3-dev这种连名字都搜不到的依赖有啥办法找到它的源码吗？

@空白可以先apt search 看看相关的，有时候可能是名字搞错了导致没有的，比如我在ubuntu 22.04上测试是有相关的包，只是版本更新些，初次之外，还可以到ros功能包专用的索引网站上搜索，具体请见：https://fishros.org.cn/forum/topic/111

另外关于你缺的这个包，是有被打包上传的，具体地址为：https://mirrors.tuna.tsinghua.edu.cn/ros2/ubuntu/pool/main/i/ignition-gazebo3/

应该是你的源有问题

@小鱼收到，谢谢小鱼
