Trusty will have ESM support until Apr 25, 2024.

Here's a list of supported ESM releases and the dates of their EOL-ESM:

Ubuntu 14.04 LTS "Trusty Tahr" : Apr 25, 2024
Ubuntu 16.04 LTS "Xenial Xerus": Apr 26, 2026
Ubuntu 18.04 LTS "Bionic Beaver": Apr 26, 2028
Ubuntu 20.04 LTS "Focal Fossa" : Apr 23, 2030
Ubuntu 22.04 LTS "Jammy Jellyfish" : Apr 21, 2032

All information provided by the ubuntu-distro-info utility found in the 
distro-info package.

$ ubuntu-distro-info -f --series=trusty --days=eol-esm
Ubuntu 14.04 LTS "Trusty Tahr" 665

$ date -d +665days

that list appears to be the standard /etc/apt/sources.list that would 
have been included in the install of 14.04. If OP want to upgrade an 
unsupported release that's reached EOL, he would need change all the 
urls to point to old-releases.ubuntu.com

For example:
deb http://us.archive.ubuntu.com/ubuntu/ trusty main restricted would be 
changed to
deb http://old-releases.ubuntu.com/ubuntu/ trusty main restricted

For upgrading to 16.04 he'd need to change
deb http://old-releases.ubuntu.com/ubuntu/ trusty main restricted
to
deb http://old-releases.ubuntu.com/ubuntu/ xenial main restricted

And so on

Not sure what the procedure is if OP's system is supported under ESM 
since I believe ESM systems use a different repo server to pull updates 
from. Plus not sure if ESM for Trusty would automatically cover an 
upgrade to Xenial. I highly doubt it.
