Question

apt-get 404 Not found errors anywhere

I never had a 404 issue like that. I did not change anything. I mentioned the issue when I tried to install something. So I’ve tried a simple update, which also gives a huge number of 404’s. I have no idea how to fix. Must be something on DO side?

Ubuntu 14.10 (Utopic Unicorn) reached “End of Life” on July 23, 2015 and is no longer supported. Ubuntu has recently remove it from their official mirrors. If you still require the Apt repositories for it, you’ll need to edit your /etc/apt/source.list to point to:

http://old-releases.ubuntu.com/

We’ve also set up a mirror for it at:

http://mirrors.digitalocean.com/ubuntu-old

Though you are strongly encouraged to upgrade to a more recent release. Security updates are no longer provided for any packages in 14.10. We are providing that repository as a convenience and temporary work around for those who haven’t upgraded to a supported release yet.

@asb : Thanks, it really worked for me by replacing Utopic (archive.ubuntu.com) source urls with http://old-releases.ubuntu.com/ .

thanks for article , after updating source.list it worked
