“apt-get update” 给出“W：无法获取 http://archive.scrapy.org/ubuntu/dists/scrapy/...”

Question

操作系统：Ubuntu 14.04

我尝试运行“sudo apt-get update”，但结果却导致与 Scrapy 相关的错误。我甚至“清除”(卸载)了 Scrapy，但仍然出现此错误。

Answer 1

检查/etc/apt/sources.list.d/目录中是否存在 scrapy。
还要检查此文件：/etc/apt/sources.list如果有条目，则删除指向 scrapy 的行。

此后，sudo apt update应该不再显示这些错误消息。

Answer 2

所以我做了这两个步骤

sudo mv /etc/apt/sources.list.d/scrapy.list /etc/apt/sources.list_deleted

sudo mv /etc/apt/sources.list.d/scrapy.list.save /etc/apt/sources.list_save_deleted

sudo apt-get update
