@佳崴在 ros安装报错：文件尺寸不符中说：

您使用的镜像正在同步中？ [IP: 192.168.111.241 8081]\n'

真的有这个ip，你看一下你的报错，去请求这个ip拿数据了，这个ip是一个局域网ip，校园网之类的，建议你换个网络试试，然后仔细检查下是不是经过什么代理之类的了，代理的地址应该就是这个ip。

佳崴

@September 可能是代理的问题，因为我用的是校园网，但是我是把下载源换成了阿里源，然后用ROS wiki 上的正常安装步骤安装完了

小鱼

@佳崴感谢反馈，是阿里云的ROS源吗？方便给个地址，我加到一键安装里。

佳崴

@小鱼只是ubuntu的下载源
https://developer.aliyun.com/mirror/ubuntu?spm=a2c6h.13651102.0.0.5bc71b11fSxLI9

小鱼

@佳崴哈哈，那就很奇怪了，因为你报错的是ROS的源
