linode | ubuntu | sudo apt-get update | mirror 404 error - linux

Question

On Linode (Ubuntu 16.10), after enabling UFW firewall via
sudo ufw allow OpenSSH
sudo ufw enable
sudo ufw allow in "Apache Full"
(though I'm not completely sure the firewall setup is the source of my issues...)
sudo apt-get update is giving me the following message:

I've tried sudo apt-get dist-update to no avail (also gives 404 errors).
I've also done unset http_proxy and unset https_proxy;
apt-get -o Acquire::ForceIPv4=true update - it still fails when using IPv4
I can ping 8.8.8.8 just fine.
...nothing's worked yet. Anyone have any idea how to fix this?

Answer 1

Response from Linode Support:
It looks like you are using an Ubuntu versions that's reached its end of life status.
https://wiki.ubuntu.com/Releases
You can reference the following link to see if you are able to update this in another manner. The other option is deploy an updated Ubuntu image for your server and copy your data over to the new disk.

Answer 2

I was stuck on this as well. But I got it working.
I had to replace "us.archive.ubuntu.com" and "security.ubuntu.com" in /etc/apt/sources.list WITH "old-releases.ubuntu.com" and then I was able to finish downloading some of the packages, like Ayush Kumar said in sudo apt-get update fail on Ubuntu 17.04.
For the other updates that were listed by my Hosting company, Linode, I used the following:
I had to use the --allow-unauthenticated flag with sudo apt-get update.
sudo apt-get update --allow-unauthenticated
Then I was able to finish updating.
