rosdepc update常见错误及解决方案

小鱼

这两天有不少小伙伴遇到rosdepc update更新失败问题，主要有两个，这里小鱼介绍下并提供解决方案。

一、使用rosdepc update后出现Expected file type is 'distribution'

这个问题，应该是rosdistro仓库修改了些东西造成的humble版本更新时的bug，可以通过下面的命令指定更新的ros版本解决。

ERROR: Rosdep experienced an error: Expected file type is 'distribution'
Please go to the rosdepc page [1] and file a bug report with the stack trace below.

发生错误了，请关注微信公众号：鱼香ROS，找小鱼反馈哦

rosdepc version: 0.21.0

    assert 'type' in data, "Expected file type is '%s'" % DistributionFile._type
AssertionError: Expected file type is 'distribution'

解决方案

使用下面的命令代替rosdepc update

rosdepc update --rosdistro=$ROS_DISTRO

如果遇到错误可以将$ROS_DISTRO替换为你的ROS版本名称

rosdepc update --rosdistro=你的ROS版本名称

比如

rosdepc update --rosdistro=melodic
rosdepc update --rosdistro=kinetic

二、Ubable to process source [xxxx/fuerte.yaml]

这个直接忽略即可，不影响使用。

@小鱼在 rosdepc update常见错误及解决方案中说：

rosdepc update --rosdistro=$ROS_DISTRO

一键装机里面的 rosdepc update 应该是没有问题，大概是网络的原因，我第一次也没有成功，多来了几次就成功了

逐。

@小鱼你好，我希正在制作一个ros的docker镜像，但是在ubuntu容器中只能通过root权限运行指令（可能是镜像太简洁所以没有用户管理系统，只有root），所以运行rosdep update也是在root下面进行的，报错说无法运行，请问有何解决方法么

小鱼

@717341215 支持的，你要安装和init update 都用root权限就行

@小鱼这边提示安装成功了但是我使用rosdepc update显示找不到命令rosdepc

@490872561 没装成功

请问出现图中could not detect OS 算更新有问题吗？
我跑gazebo仿真程序的时候也会报这个错误。
