問題
執行這個命令sudo apt-get update, 會遇到如下提示
W: The repository 'https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial Release' does not have a Release file.
解決
直接在apt源里面找到對應的, 文件然后注釋即可.
$ sudo grep -rwn docker /etc/apt/
Binary file /etc/apt/trusted.gpg matches
/etc/apt/sources.list_bak:56:deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
/etc/apt/sources.list_bak:57:# deb-src [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
/etc/apt/sources.list:56:deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
/etc/apt/sources.list:57:# deb-src [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
Binary file /etc/apt/trusted.gpg~ matches
/etc/apt/sources.list.save:56:deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
/etc/apt/sources.list.save:57:# deb-src [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
注釋掉對於的行數即可. 前面加上# pound key.
# deb [arch=amd64] https://mirrors.ustc.edu.cn/docker-ce/linux/ubuntu xenial stable
然后在執行 sudo apt-get update
Reading package lists... Done
小結
遇到類似的問題, 直接就是找到對應的source.list里面有這個, 屏蔽了即可.
