请教一下源的问题

[haoarthur]

O大，我尝试了多个国内源和国外ubuntu原源，总会有几个相同的地方报错，我通过连接进去看确实不存在这个包，请问像这样的问题如何解决呢？

再一个就是，我访问github特别慢，能不能在armbian通过访问镜像网站来提速，实现升级什么的。目前我就是访问的镜像网页跟你留言的。

armbian:~:# armbian-sync
[ INFO ] Armbian PLATFORM: [ amlogic ]

谢谢。

想装docker也会提示这样的错误
armbian::curl -fsSL https://get.docker.com -o get-docker.sh

armbian:: sh get-docker.sh
