gpg key for ubuntu trusty-security. (Deprecation of apt-key)

Question

I need your help with apt-key deprecation issue.

I am aware that this topic has been discussed countless times however my query is related to finding the correct gpg-key.

Since I upgraded my Ubuntu from 20.04 LTS to 22.04 LTS, I am getting the following warning.

All packages are up to date.
W: http://security.ubuntu.com/ubuntu/dists/trusty-security/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

I know the problem lies with the misplaced gpg key, so I tried to follow https://www.omgubuntu.co.uk/2022/06/fix-apt-key-deprecation-error-on-ubuntu to fix the issue. However, I could not find the key for trusty-security in the apt-key list.

Could anyone help me identify the correct key for trusty-security?

The key list is as follows.

sudo apt-key list
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

Why would you want it? trusty refers to the 2014-April (14.04) release which reached EOSS or end of standard support in April 2019, thus why would it have anything useful/safe for a modern Ubuntu system? It should be removed ! — guiverc, Aug 22 '22 at 03:29
Sorry, but I am not sure about its functionality. Every time I upgraded to the newer version, Ubuntu kept it as it was in the older version (including the repository). Also, in the repository list, it is labeled as "Important Security Updates," so I thought it would be necessary. If it's okay to remove it, I will do so. — sk27, Aug 23 '22 at 11:38
When you release-upgraded it would have been disabled, starting with when upgrading from 14.04 to 16.04 (ie. a "#" added to the start of the line so it was ignored), so someone with sudo rights would have had to re-enable it (removed the "#" at the start of the line), or IF this is a desktop system re-enabled it via GUI tool after each release-upgrade. trusty was 14.04; xenial was 16.04, bionic was 18.04, focal was 20.04 & jammy is 22.04. The default is to disable (ie. comment out) as it's not removed on upgrade. — guiverc, Aug 23 '22 at 11:50
I understand. In that case, I will remove it from the system. Thank you for helping me. — sk27, Aug 24 '22 at 01:32
