Linux linode | ubuntu | sudo apt get update | mirror 404错误

在Linode（Ubuntu 16.10）上，通过

sudo ufw allow OpenSSH
sudo ufw enable
sudo ufw allow in "Apache Full"

（虽然我不完全确定防火墙设置是我问题的根源…）

sudo apt get update

向我发送了以下消息：

我尝试了

sudo-apt-get-dist-update

，但没有成功（也给出了404个错误）

我还做了

取消设置http_代理

和

取消设置https_代理

apt get-o Acquire:：ForceIPv4=true update

-使用IPv4时仍会失败

我可以

ping 8.8.8.8

很好

…什么都没用。有人知道如何解决这个问题吗？

Linode支持部门的回应：

看起来你正在使用的Ubuntu版本已经达到了生命终结状态

您可以参考以下链接，查看是否能够以其他方式更新此内容。另一个选项是为服务器部署更新的Ubuntu映像，并将数据复制到新磁盘上

我也被困在这个问题上。但是我让它工作了

我不得不将

/etc/apt/sources.list

中的“us.archive.ubuntu.com”和“security.ubuntu.com”替换为“old releases.ubuntu.com”，然后我就可以完成一些软件包的下载，就像Ayush Kumar在年所说的那样

对于我的托管公司Linode列出的其他更新，我使用了以下内容：

我必须使用sudo apt get update的

--allow unauthenticated

标志

sudo apt get update--允许未经验证的

然后我就可以完成更新了
 您需要在UFW设置中允许端口
53
和
123
。OpenSSH默认为
22
，Apache默认为
80
443
和
8080
。@Zak我尝试了
sudo ufw allow 123/udp
和
sudo ufw allow 53/udp
，没有更多的材料-->我也遵循了所有这些说明。没有骰子。我还尝试过禁用防火墙，然后执行apt-get，nothing.Stack Overflow是一个解决编程和开发问题的网站。这个问题似乎离题了，因为它与编程或开发无关。请参见帮助中心中的。也许或者会是一个更好的提问的地方。
