I was applying updates to my AWS Ubuntu 14.04 servers. I used this command:
sudo apt-get update
It work for all of them, except one server.
I get this error at the end:
W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/raring/main/binary-amd64/Packages 404 Not Found [IP: 18.104.22.168 80] W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/raring/universe/binary-amd64/Packages 404 Not Found [IP: 22.214.171.124 80] E: Some index files failed to download. They have been ignored, or old ones used instead.
I tried to do an upgrade. I ran this:
# sudo apt-get upgrade
I saw this:
Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages have been kept back: lxc-docker 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
What should I do to get the updates to apply?
