但对我来说没有解决方案。我已经启用了所有源 -
也尝试过sudo apt-get update很多次，但它又回来了
有些输出类似这样的内容：无法下载或找到软件包或类似内容 -

我现在应该怎么做
答案1
由于每次尝试连接到提供 Ubuntu 软件包的服务器时都会出现相同 IP 地址的错误，因此我认为您已使用 IP 80.112.143.217 和端口 80 配置了 Web 代理。
在 Google 中快速搜索后我发现，该 IP 确实与公共网络代理相关联。
目前它没有响应任何查询，所以我现在可能没有运行。尝试删除代理设置：System settings-> Network-> Network proxy。删除或将代理地址更改为正常运行的地址，然后单击Apply system wide。
答案2
似乎您正在使用代理来连接存储库。/etc/apt/apt.conf 中的配置文件可能有误。请检查内容。其格式应为：
Acquire::http::proxy "http://<username>:<password>@<proxy>:<port>/";
Acquire::ftp::proxy "ftp://<username>:<password>@<proxy>:<port>/";
Acquire::https::proxy "https://<username>:<password>@<proxy>:<port>/";
用户名不能是电子邮件!!! - 用户名和密码可以为空 - 删除 < >
如果您能够直接连接到互联网，只需删除 /etc/apt/apt.conf 文件即可。（也建议先备份它：））所有这些信息适用于 ubuntu 12.04 到 14.04（据我所知）
