I get 3 warnings after Ubuntu 22.04 update on a Digital Ocean LAMP stack droplet.

W: http://repo.mysql.com/apt/ubuntu/dists/bionic/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
W: https://repos.insights.digitalocean.com/apt/do-agent/dists/main/InRelease: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.
W: http://pkg.cloudflare.com/dists/trusty/Release.gpg: Key is stored in legacy trusted.gpg keyring (/etc/apt/trusted.gpg), see the DEPRECATION section in apt-key(8) for details.

How to move the keys to the right location and delete the old keys?

EDIT

sudo apt-key list

This answer is a customization of the one provided by matigo user here. You need to export the GPG key from the deprecated keyring and store it in /usr/share/keyrings for every repo.

  1. Let's begin with DigitalOcean key. Open Terminal and export the 9FE3 B226 BD77 5196 D8C2 E599 DE88 104A A4C6 383F key:

    apt-key export A4C6383F | sudo gpg --dearmour -o /usr/share/keyrings/digitalocean-agent.gpg

    Note: The A4C6383F value comes from the last 8 characters of the pub code from the apt-key list output.

  2. Now we can update our apt source file /etc/apt/sources.list.d/digitalocean-agent.list), adding a signed-by tag. Open it by:

    sudo -H gedit /etc/apt/sources.list.d/digitalocean-agent.list

    and add the tag [arch=amd64 signed-by=/usr/share/keyrings/digitalocean-agent.gpg] just after the deb keyword and before the URL.

    I don't know the exact content of digitalocean-agent.list, but it should be eventually something similar to:

    deb [arch=amd64 signed-by=/usr/share/keyrings/microsoft.gpg] packages.microsoft.com/repos/edge stable main

  3. Run sudo apt update to confirm the message is gone

  4. If the message is gone, remove the original signature:

    sudo apt-key del A4C6383F

  5. Repeat the steps for cloudflare-main.list, generating the cloudflare-main.gpg key starting from 8CACCBF8 key.

  6. Repeat the steps for mysql.list, generating the mysql.gpg key starting from 5072E1F5 key.

Consider that the messages you have are only warnings: if something goes bad, restore the files as they are and keep the warnings, they are not harmful.
