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)).
