阿里云安装Docker添加源报错E: Malformed entry XX in list file /etc/apt/sources.list (Component)

E: Malformed entry 60 in list file /etc/apt/sources.list (Component)

E: The list of sources could not be read.

在阿里云上添加了Docker官方的下载源后,升级包(apt-get update)报出如上的错误.

没办法只好注释掉了其中的一个源路径:

deb [arch=amd64] https://download.docker.com/linux/ubuntu stable

只留下了:

deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable

再次更新源不再报错.
